Determinants of objective and subjective quality of life in first-time-admission schizophrenic patients in Poland: a longitudinal study

Context and Expectations Matter: Social, Recreational, and Independent Functioning among Youth with Psychosis in Chennai, India and Montreal, Canada

OBJECTIVES

Most cross-cultural psychosis research has focused on a limited number of outcomes (generally symptom-related) and perspectives (often clinician-/observer-rated). It is unknown if the purported superior outcomes for psychosis in some low- and middle-income countries extend to patient-reported measures of social, recreational, and independent functioning. Addressing this gap, this study aimed to compare these outcomes in first-episode psychosis at a high-income site and a lower middle-income site.

METHODS

Patients receiving similarly designed early intervention for psychosis in Chennai, India (N = 164) and Montreal, Canada (N = 140) completed the self-reported Social Functioning Scale-Early Intervention, which measures prosocial, recreation, and independence-performance functioning. Their case managers rated expected independence-performance functioning. Both sets of assessments were done at entry and Months 6, 18, and 24. Linear mixed model analyses of differences between sites and over time were conducted, accounting for other pertinent variables, especially negative symptoms.

RESULTS

Linear mixed models showed that prosocial, recreation, and independence-performance functioning scores were significantly higher in Montreal than Chennai and did not change over time. Expected independence-performance was also higher in Montreal and increased over time. Negative symptoms and education independently predicted prosocial, recreation, and expected independence-performance functioning. When added to the model, expected independence-performance predicted actual independence-performance and site was no longer significant. At both sites, prosocial and recreation scores were consistently lower (<40%) than independence-performance (40-65%).

CONCLUSION

This is the first cross-cultural investigation of prosocial, recreation, and independent functioning in early psychosis. It demonstrates that these outcomes differ by socio-cultural context. Differing levels of expectations about patients, themselves shaped by cultural, illness, and social determinants, may contribute to cross-cultural variations in functional outcomes. At both sites, social, recreational, and independent functioning were in the low-to-moderate range and there was no improvement over time, underscoring the need for effective interventions specifically designed to impact these outcomes.

Impact of negative symptoms on health-related quality of life in schizophrenia

Evidence regarding the association of Negative Symptoms (NS) dimensions with Health-related Quality of Life (HRQoL) is limited and no prior study has looked into contributions of NS domains on HRQoL. This study bridges the gap by examining the associations of NS, its two dimensions (Motivation and Pleasure, and Emotional Expressivity) and five domains (Anhedonia, Avolition, Asociality, Blunted affect and Alogia) with HRQoL in schizophrenia. 274 individuals with schizophrenia were assessed on the Positive and Negative Syndrome Scale (PANSS) and Brief Negative Symptom Scale (BNSS). PANSS scores were mapped to EuroQol five-dimensional (EQ-5D-5L) utility scores using an algorithm previously validated in Singapore, and the resulting EQ-5D-5L scores were used as a measure of HRQoL. Multiple linear regression analyses of the two NS dimensions and five NS domains against EQ-5D-5L showed that a lower severity of NS, specifically that of the Motivation and Pleasure (MAP) dimension and asociality domain was associated with higher HRQoL. Our findings highlight the importance of targeting NS, particularly MAP and asociality, in improving HRQoL in schizophrenia.

Perceived stress, social functioning and quality of life in first-episode psychosis: A 1-year follow-up study

AIM

Quality of life (QoL) has been widely studied in people with schizophrenia. In the early phases of psychosis, it remains often impaired even after the remission of psychotic symptoms. The aim of this study was to explore QoL and social functioning during the first year after a first-episode psychosis (FEP), and to study potential moderating effects of stress measures.

METHODS

Here, 61 FEP subjects and 55 healthy controls (HCs) were included. Sociodemographic data and clinical variables were collected through a semi-structured interview. Stress measures, social functioning and QoL were assessed with the Holmes-Rahe Social Readjustment Rating Scale, the Perceived Stress Scale, the Social Adaptation Self-Scale and the Euro-QoL-5D, respectively. Analysis of variance was employed with repeated measures and a mediation analysis at baseline and at 1-year follow-up was carried out.

RESULTS

Patients reported lower QoL, poorer social functioning and more stress than HC. FEP patients significantly improved in QoL and stress measures over time, but not in social functioning. Perceived stress mediated the association between poorer social functioning and lower QoL.

CONCLUSIONS

Social functioning at baseline may determine QoL over a 1-year follow-up period. Despite the improvement in most measures, patients do not achieve the level of well-being as the healthy group.

Patterns and predictors of trajectories for subjective quality of life in patients with early psychosis: Three-year follow-up of the randomized controlled trial on extended early intervention

OBJECTIVE

Subjective quality of life is an important outcome of psychotic disorders. However, longitudinal course of subjective quality of life in the early illness stage is under-studied. We aimed to investigate the patterns and baseline predictors of subjective quality of life trajectories over 3 years in early psychosis patients, utilizing growth mixing modeling analysis, in the context of a 3-year follow-up of a randomized controlled trial comparing 1-year extension of early intervention with step-down psychiatric care for first-episode psychosis.

METHOD

One hundred sixty Chinese patients were recruited from specialized early intervention program for first-episode psychosis in Hong Kong after they had completed this 2-year early intervention service, and underwent 1-year randomized controlled trial as well as 2-year post-randomized controlled trial follow-up (i.e. 3-year follow-up). Assessments on premorbid adjustment, onset profile, psychopathology, functioning and treatment characteristics were conducted. Individual class membership of subjective quality of life trajectory derived from growth mixing modeling was based on the 36-Item Short Form Health Survey mental component summary scores measured at four different time-points (baseline, 1, 2 and 3 years) among 142 participants across 3-year follow-up.

RESULTS

Three distinct subjective quality of life trajectories were identified including higher-improving (68.3%, n = 97), lower-stable (24.6%, n = 35) and deteriorating (7%, n = 10) trajectories. Age of onset; duration of untreated psychosis; depressive, positive and negative symptoms; and intervention condition were significantly different between good (higher-improving trajectory) and poor (combined lower-stable and deteriorating trajectories) trajectory groups. Multiple regression analysis revealed that younger age of onset, more severe depression and receipt of step-down care independently predicted poor subjective quality of life trajectory.

CONCLUSION

Approximately one-third of patients displayed poor subjective quality of life trajectory in the early phase of psychotic illness. Our results affirm depression as a critical determinant of prospective subjective quality of life and underscores positive effect of extended early intervention on sustained subjective quality of life improvement. Further longitudinal research is warranted to facilitate better characterization of subjective quality of life course patterns and development of targeted intervention to optimize subjective quality of life in patients with early psychosis.

Quality of life in patients with severe mental illness: a cross-sectional survey in an integrated outpatient health care model

PURPOSE

This study (a) assessed quality of life (QoL) in a patient sample with severe mental illness in an integrated psychiatric care (IC) programme in selected regions in Germany, (b) compared QoL among diagnostic groups and (c) identified socio-demographic, psychiatric anamnestic and clinical characteristics associated with QoL.

METHODS

This cross-sectional study included severely mentally ill outpatients with substantial impairments in social functioning. Separate dimensions of QoL were assessed with the World Health Organisation's generic 26-item quality of life (WHOQOL-BREF) instrument. Descriptive analyses and analyses of variance (ANOVAs) were conducted for the overall sample as well as for diagnostic group.

RESULTS

A total of 953 patients fully completed the WHOQOL-BREF questionnaire. QoL in this sample was lower than in the general population (mean 34.1; 95% confidence interval (CI) 32.8 to 35.5), with the lowest QoL in unipolar depression patients (mean 30.5; 95% CI 28.9 to 32.2) and the highest in dementia patients (mean 53.0; 95% CI 47.5 to 58.5). Main psychiatric diagnosis, living situation (alone, partner/relatives, assisted), number of disease episodes, source of income, age and clinical global impression (CGI) scores were identified as potential predictors of QoL, but explained only a small part of the variation.

CONCLUSION

Aspects of health care that increase QoL despite the presence of a mental disorder are essential for severely mentally ill patients, as complete freedom from the disorder cannot be expected. QoL as a patient-centred outcome should be used as only one component among the recovery measures evaluating treatment outcomes in mental health care.

Perceived stress mediates the relationship between social adaptation and quality of life in individuals at ultra high risk of psychosis

AIM

Quality of life (QoL) and social functioning have emerged as good predictors of the outcome of psychotic disorders. Poor QoL and social functioning are usually present before the onset of the first episode of psychosis. Our study aimed to explore the relationship between social adaptation and QoL in young people at risk of psychosis (ultra-high-risk, UHR) and healthy controls (HCs), and to investigate potential mediating effects of stress measures (perceived stress, stressful life events).

METHODS

The study included 55 UHR subjects and 40 HC. Social functioning was assessed with the Social Adaptation Self-evaluation Scale (SASS). Stress measures included the assessment of stressful life events and perceived stress. We compared stress and QoL measures between UHR and HC, and also compared UHR with low or normal social adaptation. A mediation analysis was performed to explore whether stress measures mediated the relationship between social adaptation and QoL.

RESULTS

UHR were less frequently employed and reported more stress, poorer QoL and lower social adaptation than HC. QoL and social adaptation were associated with stress measures. UHR with low social adaptation reported more perceived stress and less QoL than UHR with normal social adaptation and HC. Perceived stress mediated the relationship between social adaptation and QoL.

CONCLUSIONS

Social adaptation is less developed in UHR subjects than in healthy subjects and has a negative impact on quality of life. This association is mediated by perceived stress.

Longitudinal evidence for a relation between depressive symptoms and quality of life in schizophrenia using structural equation modeling

Patients diagnosed with schizophrenia often report a low quality of life (QoL). The purpose of this study was to investigate whether we could replicate a cross-sectional model by Alessandrini et al. (2016, n = 271) and whether this model predicts QoL later in life. This model showed strong associations between schizophrenia spectrum symptoms and depressive symptoms on QoL, but lacked follow-up assessment. This model was adapted in the current study and the robustness was investigated by using a longitudinal design in which the association between baseline variables (including IQ, depression, schizophrenia spectrum symptoms as well as social functioning) and QoL during 3-years of follow-up was investigated. We included patients with a non-affective psychotic disorder (n = 744) from a prospective naturalistic cohort-study. In the cross-sectional model, with good measure of fit, both depression as well as social functioning was associated with QoL (direct path coefficient -0.28 and 0.41, respectively). Additionally, the severity of schizophrenia spectrum symptoms was highly associated with social functioning (direct path coefficient -0.70). Importantly, the longitudinal model showed good measures of fit, which strengthens the validity of the initial model and highlights that depression prospectively affect QoL while schizophrenia spectrum symptoms prospectively influence QoL via social functioning. The negative, longitudinal impact of a depression on QoL highlights the need to focus on treatment of this co-morbidity.

Trends in Subjective Quality of Life Among Patients With First Episode Psychosis-A 1 Year Longitudinal Study

Quality of life (QoL) is often used as an outcome assessment in programs treating patients with first-episode psychosis (FEP). The aim of this study was to examine the longitudinal trend of subjective QoL among patients with FEP and identify the potential influence of patients' social-demographic/lifestyle factors on the trend of QoL. Two hundred and eighty subjects participated in the study. Patient's demographics and subjective QoL were collected at baseline, 6 months and 1 year follow-up. Data were analyzed with a fixed-effect general linear regression model. Subjective QoL demonstrated significant trends of improvement in all four subdomains (physical health, psychological health, social relationships, and environment). Compared with unemployed participants, employed participants were significantly associated with better social relationships (p = 0.005) and environment (p = 0.029) after adjusting for age and gender. Moderation analysis demonstrated a significant improvement of physical health, social relationships, and environment for participants with a higher level of educational achievement, but not for participants with a lower level of educational achievement. Our results indicate that patients with FEP experienced significant improvement in subjective QoL over a 1 year period. Being employed was associated with overall better social relationships and environment among patients with FEP and higher educational achievement was associated with improvement of physical health, social relationship, and environment. Hence, educational achievement and employment could be considered for future optimization of early psychosis intervention programs.

Depression and functioning are important to subjective quality of life after a first episode psychosis

BACKGROUND

Subjective quality of life (S-QoL) is an important outcome measure in first-episode psychosis, but its associations with clinical predictors may vary across the illness course. In this study we examine the association pattern, including both direct and indirect effects, between specific predefined clinical predictors (insight, depression, positive psychotic symptoms and global functioning) and S-QoL the first ten years after a first-episode psychosis.

METHODS

Three hundred and one patients with a first-episode psychosis were included at first treatment, and reassessed at 3 months, 1 year, 2 years, 5 years and 10 years after inclusion. At 10-year follow-up 186 participated. S-QoL was assessed with Lehman's Quality of Life Interview. Applying a structural equation model, we investigated cross-sectional association patterns at all assessments between the predefined clinical predictors and S-QoL.

RESULTS

At baseline, only depression was significantly associated with S-QoL. At all follow-up assessments, depression and functioning showed significant associations with S-QoL. Insight was not associated with S-QoL at any of the assessments. Better insight, less depressive symptoms and less positive psychotic symptoms were all associated with higher functioning at all assessments. Functioning seems to mediate a smaller indirect inverse association between positive psychotic symptoms and S-QoL. The association pattern was stable across all follow-up assessments.

CONCLUSIONS

Together with depression, functioning seems to be important for S-QoL. Functioning seems to be a mediating factor between positive symptoms and S-QoL. A focus on functional outcome continues to be important.

Calidad de vida en pacientes con esquizofrenia de origen Aymara en la zona Centro-Sur de los Andes

El objetivo de este estudio consistió en comparar la calidad de vida (CV) de pacientes con esquizofrenia pertenecientes al grupo étnico aymara de los Andes Centro-Sur, con pacientes no Aymara. En este estudio transversal participaron 253 pacientes de tres clínicas de salud mental en Chile, Perú y Bolivia. Se recogieron datos sociodemográficos y características clínicas. La calidad de vida se evaluó utilizando el Cuestionario S-QoL18. Los análisis comparativos exploraron las diferencias de QoL entre los pacientes Aymara y no Aymara. Los participantes de origen Aymara tuvieron puntuaciones de CV más bajos en comparación con los pacientes no Aymara para el Índice total, las relaciones familiares y la dimensión de vida sentimental. Los ingresos familiares mensuales y la duración del trastorno fueron significativamente más bajos en los pacientes Aymara. Nuestro estudio soporta la hipótesis de una peor CV en pacientes aymaras con esquizofrenia.

Association between social functioning and prefrontal cortex function during a verbal fluency task in schizophrenia: A near-infrared spectroscopic study

AIM

Impaired social functioning is a common characteristic of patients with schizophrenia. Social functioning requires the complex operation of various executive functions. Deficits in the prefrontal cortex (PFC) have been implicated in executive dysfunction. Here we aimed to clarify the relation between subjectively and objectively assessed social functioning, and their associations with PFC function in patients with schizophrenia.

METHODS

Twenty-three patients and 22 age- and sex-matched healthy controls (HC) were assessed. In the schizophrenia group, self- and caregiver-rated social functioning were measured using the Specific Level of Functioning Assessment (SLOF). The hemodynamic responses elicited by a verbal fluency task (VFT) in three regions of interest in the frontotemporal area were measured using multi-channel near-infrared spectroscopy (NIRS). We also investigated psychiatric symptoms, neurocognition, and cognitive insight to assess possible confounding factors.

RESULTS

Significant positive correlations were found between self- and caregiver-rated SLOF composite scores and three subdomain scores. Self- and caregiver-rated SLOF composite scores were significantly associated with dorsolateral PFC and frontopolar cortex (DLPFC/FPC) activation during the VFT. Psychiatric symptoms, global functioning, neurocognition, and cognitive insight were not associated with NIRS signals. General psychopathology was associated with NIRS signals in the ventrolateral PFC and the anterior temporal cortex. DLPFC and FPC activity may be associated with social functioning in patients with schizophrenia.

CONCLUSION

Our results suggest that the two distinct assessments of social functioning were significantly correlated. Moreover, DLPFC and FPC function was strongly associated with social functioning and the ability to carry out daily life in patients with schizophrenia.

Subjective and objective quality of life at first presentation with psychosis

AIM

Quality of life (QOL) in first-episode psychosis (FEP) is impaired when compared to non-clinical controls and several clinical factors including symptoms and untreated psychosis have been linked with poorer QOL. Measurement methods are varied, however, resulting in inconsistent findings and there is a need to simultaneously combine subjective and objective measures of QOL.

METHODS

We examined both subjective (n = 128) and objective QOL (n = 178) in a catchment area cohort of individuals with FEP (n = 222) to determine correspondence between patient satisfaction and clinician-rated functional domains. We also examined the contribution of sociodemographic and clinical characteristics to both subjective and objective QOL.

RESULTS

There were complex relationships between subjective and objective QOL domains in that patient's assessments of health status (psychological well-being, symptoms/outlook, physical health) were not correlated with clinicians but there were strong correlations between social functioning domains (occupation, social relations, financial status and activities of daily living) assessed by patients and clinicians. Longer duration of untreated psychosis, being treated as an inpatient, higher positive symptoms and poorer social functioning in client-rated QOL domains predicted poorer objective QOL.

CONCLUSION

We found that both subjective and objective assessments of QOL displayed a degree of clinical utility demonstrated by relationships between clinical factors and both QOL perspectives. Moreover, the lack of association between patient characteristics and QOL shows some potential malleability of QOL outcomes through intervention as there were several clinical factors linked with both subjective and objective QOL.

Clinical and treatment-related determinants of subjective quality of life in patients with first-episode psychosis

Subjective quality of life (SQoL) has been increasingly studied in first-episode psychosis (FEP). Prior research primarily examined the impact of psychiatric symptoms on SQoL. Relationship between treatment-related factors and SQoL is under-studied. In this study, 159 Chinese patients who had completed 2-year treatment from early intervention service in Hong Kong were recruited. Assessments on premorbid adjustment, clinical profiles including social anxiety measure, functioning, antipsychotic-induced extrapyramidal side-effects and attitude toward medication treatment were conducted. SQoL was evaluated by Chinese version SF36 which generated mental and physical component summary (MCS and PCS) scores for analysis. Our results showed that more severe positive symptoms, higher level of depression, greater social anxiety, more negative attitude toward antipsychotic medications and greater degree of akathisia independently predicted lower MCS score. Higher social anxiety level and poorer functioning predicted lower PCS score. Our results indicate that affective and positive symptoms, functioning, and treatment-related variables are critical determinants of SQoL in FEP patients. These identified factors thus represent potentially malleable therapeutic targets for early detection and prompt intervention to promote enhancement of SQoL in the early stage of illness.

Subjective quality of life in first-episode psychosis. A ten year follow-up study

Subjective quality of life (S-QoL) is an important outcome measure in first episode psychosis (FEP). The aims of this study were to describe S-QoL-development the first 10-years in FEP patients and to identify predictors of this development.

METHODS

A representative sample of 272 patients with a first episode psychotic disorder was included from 1997 through 2000. At 10 year follow-up 186 patients participated. QoL was measured by the Lehman's Quality of Life Interview. Linear mixed model analyses were performed to investigate longitudinal effects of baseline psychiatric symptoms and socio-economic variables and the effects of changes in the same variables on S-QoL-development.

RESULTS

S-QoL improved significantly over the follow-up period. More contact with family and a better financial situation at baseline had a positive and longstanding effect on S-QoL-development, but changes in these variables were not associated with S-QoL-development. Higher depressive symptoms and less daily activities at baseline both had a negative independent effect, but a positive interaction effect with time on S-QoL-development indicating that the independent negative effect diminished over time. In the change analysis, increased daily activities and a decrease in depressive symptoms were associated with a positive S-QoL-development.

CONCLUSIONS

Treatment of depressive symptoms and measures aimed at increasing daily activities seem important to improve S-QoL in patients with psychosis. More contact with family and a better financial situation at baseline have a long-standing effect on S-QoL-development in FEP patients.

Quality of life and clinical characteristics in a nonselected sample of patients with schizophrenia

BACKGROUND

Patients with schizophrenia experience low quality of life (QOL).

AIMS

To examine QOL in these patients and the relation between QOL and illness duration, adjusted daily doses (ADDs) of antipsychotics, body mass index (BMI), waist circumference and smoking.

METHODS

In this naturalistic, cross-sectional study, 82 patients were interviewed about smoking habits. Patients completed a QOL questionnaire (World Health Organization Quality of Life-Bref) consisting of physical, psychological, social and environmental domains and had height, weight and waist circumference measured. The characteristics and QOL were correlated using multiple regression analysis.

RESULTS

QOL was significantly lower in the patients than in the general population (p < .01). In first-ever diagnosed patients, QOL was associated with BMI (regression coefficient (RC): physical -0.73, psychological -1.44 and environmental -0.55; all p < .05), ADD (RC: physical 3.71, psychological 4.37 and environmental 2.94; all p < .10) and smoking (RC: physical -0.69; p < .01). In the long-term ill patients, QOL was associated with BMI (RC: physical -1.19 and psychological -1.28; all p < .05) and illness duration (RC: physical 1.38; p < .05).

CONCLUSION

Patients experienced low QOL. Lower QOL was associated with high BMI, low ADD and smoking in first-ever diagnosed patients and with high BMI and short illness duration in long-term ill patients.

Psychosocial functioning in relation to symptomatic remission: A longitudinal study of first episode schizophrenia

OBJECTIVES

The aims of the study were: (1) to evaluate longitudinally symptomatic remission in first-episode (FE) schizophrenia, (2) to describe symptoms, social functioning and quality of life (Qol) in relation to remission status, and (3) to determine the long-term outcome of schizophrenia and its early predictors.

METHODS

Sixty-four patients were assessed 1 month after a first hospitalization (T1), 12 months (T2), 4-6 years (T3), and 7-11 years (T4) after T1. The patients were allocated to three remission groups according to their remission status over the whole observation period, e.g. stable remission (SR), unstable remission (UR) and non-remission (NR). The PANSS, Social Functioning Scale and WHOQoL were used to evaluate the patients' psychosocial functioning levels, symptomatic and functional remissions and satisfying QoL. A good outcome was defined as meeting, simultaneously, the criteria of symptomatic and functional remissions and satisfying QoL at T4, while failure to meet all of these criteria was defined as a poor outcome.

RESULTS

Among them, 17.2% patients were in stable remission, 57.8% in unstable remission and 25.0% were unremitted at all time points. The SR group had lower levels of psychopathological symptoms and reported better social functioning and QoL than the NR group. During the follow-up, the symptoms increased, social functioning slightly improved and QoL did not change. At T4, 53% of the sample had a poor outcome, which was independently predicted by the longer duration of untreated psychosis and a lack of satisfying QoL at T1.

CONCLUSIONS

Our results demonstrate that: (1) the long-term course in schizophrenia is heterogeneous and that three illness trajectories exist, (2) social functioning and QoL are only partially connected with symptomatic remission (3), the risk of a poor outcome may potentially be reduced by appropriate interventions at an early stage of the illness.

Do negative symptoms of schizophrenia change over time? A meta-analysis of longitudinal data

BACKGROUND

Negative symptoms are a core component of schizophrenia which can severely impact quality of life and functional outcomes. These symptoms are understood to be highly stable but this has not been tested in a meta-analysis, despite the wealth of longitudinal data available.

METHOD

A systematic review of the literature was conducted, with eligible studies pooled into a random-effects meta-analysis. Planned meta-regressions were conducted to evaluate the impact of factors known to induce secondary negative symptoms, in addition to other possible sources of heterogeneity.

RESULTS

The main analysis included 89 samples from 41 studies, totalling 5944 participants. Negative symptoms were found to significantly reduce in all treatment interventions, including in placebo and treatment as usual conditions, with a medium effect size (ES) present across all study conditions (ES = 0.66, 95% confidence interval 0.56-0.77, I(2) = 94.0%). In a multivariate meta-regression, only the type of scale used was found to significantly influence negative symptom change. No difference in outcome was found between studies that excluded patients with a high level of positive or depressive symptoms, compared to those that did not.

CONCLUSIONS

Negative symptoms were found to reduce in almost all schizophrenia outpatient samples. A reduction was found across all conditions, with effect sizes ranging from small to large depending upon the condition type. These findings challenge the convention that negative symptoms are highly stable and suggest that they may improve to a greater extent than what has previously been assumed.

The impact of premorbid adjustment, neurocognition, and depression on social and role functioning in patients in an early psychosis treatment program

OBJECTIVE

Functional impairments are debilitating concomitants of psychotic disorders and are present early in the illness course and, commonly, prior to psychosis onset. The factors affecting social and role functioning in early psychosis (EP) following treatment are unclear. We evaluated whether six months of participation in the PREP(R), Boston, EP treatment program, part of a public-academic community mental health center, was related to improvements in social and role functioning and whether premorbid adjustment in adolescence, baseline neurocognition, and depression symptoms predicted functional improvement.

METHOD

The Global Functioning Social and Role scales, MATRICS neurocognitive battery, and Calgary Depression Scale were assessed at baseline and six months during naturalistic treatment, while premorbid adjustment was measured at baseline. All participants were psychotic disorder patients in PREP(R) (n = 46 with social functioning and 47 with role functioning measures at both time points).

RESULTS

Large improvements were observed in role functioning (d = 0.84) and medium to large improvements were observed in social functioning (d = 0.70). Models consisting of adolescent premorbid adjustment and change in depression symptoms predicted social and role functioning change, whereas neuropsychological functioning did not.

CONCLUSIONS

Substantial improvements in social and role functioning were observed among this sample participating in a recovery-based EP program. The impact of clinical factors on social and role functioning was highlighted. Further studies of premorbid adjustment in adolescence and the treatment of depression in EP programs in controlled treatment trials are needed to confirm these findings.

Quality of life of patients with schizophrenia treated in foster home care and in outpatient treatment

BACKGROUND

The Sveti Ivan Psychiatric Hospital in Zagreb, Croatia, offers foster home care treatment that includes pharmacotherapy, group psychodynamic psychotherapy, family therapy, and work and occupational therapy. The aim of this study is to compare the health-related quality of life of patients with schizophrenia treated in foster home care with that of patients in standard outpatient treatment.

METHODS

The sample consisted of 44 patients with schizophrenia who, upon discharge from the hospital, were included in foster home care treatment and a comparative group of 50 patients who returned to their families and continued receiving outpatient treatment. All patients completed the Short Form 36 Health Survey Questionnaire on the day they completed hospital treatment, 6 months later, and 1 year after they participated in the study. The research also included data on the number of hospitalizations for both groups of patients.

RESULTS

Though directly upon discharge from the hospital, patients who entered foster home care treatment assessed their health-related quality of life as poorer than patients who returned to their families, their assessments significantly improved over time. After 6 months of treatment, these patients even achieved better results in several dimensions than did patients in the outpatient program, and they also had fewer hospitalizations. These effects remained the same at the follow-up 1 year after the inclusion in the study.

CONCLUSION

Notwithstanding the limitations of this study, it can be concluded that treatment in foster home care is associated with an improvement in the quality of life of patients with schizophrenia, but the same was not observed for the patients in standard outpatient treatment. We hope that these findings will contribute to an improved understanding of the influence of psychosocial factors on the functioning of patients and the development of more effective therapeutic methods aimed at improving the patients' quality of life.

Quality of life in a 20-year follow-up study of people suffering from schizophrenia

AIMS

1. To assess the changes in quality of life indicators in schizophrenia sufferers at three measurement points: 7, 12 and 20 years after the first hospitalization. 2. To assess changes in the level of functioning and psychopathological state. 3. To assess the relationships between quality of life, the level of functioning and the severity of symptoms.

METHOD

A sample group of fifty-two people diagnosed with schizophrenia was investigated using the Lehman's QOLQ, the GAF scale and BPRS.

RESULTS

A deterioration was noted in the subjective and objective areas of family life and health, subjectively assessed social relationships and objectively assessed finances. The better functioning sub-group returned better scores for the following objective quality of life indicators: free time, family life, health, social relationships and financial situation. The sub-group in remission obtained better results for general, subjective quality of life and for subjectively assessed health, as well as better scores for objectively assessed free time, social relationships, financial situation and health. An improvement in general, subjective quality of life was seen in the sub-group whose symptoms had grown more severe.

CONCLUSIONS

The decline in subjective and objective quality of life in the areas of health and family life, in the subjective evaluation of social relationships and in the objective assessment of financial situation was associated with a deterioration in functioning and an absence of symptom remission. The improvement in general, subjective quality of life in the sub-group with severe symptoms may be evidence of the formation of adaptive mechanisms.

Psychosocial functioning in schizophrenia: are some symptoms or demographic characteristics predictors across the functioning domains?

This study aimed to examine symptoms/demographic characteristics as predictors for psychosocial functioning among individuals with schizophrenia. The Personal and Social Performance (PSP) scale was used to assess psychosocial functioning. Other measures of interest included were the Clinical Global Impression, Severity scale, and the Marder's five-factor model of the Positive and Negative Syndrome Scale. This study included 199 participants with non-acute stage schizophrenia. Spearman correlation coefficients and stepwise multiple linear regression analyses were applied to determine the correlates and predictors of PSP domain/total scores. Younger age, earlier age of schizophrenia onset, severe illness, positive symptoms, negative symptoms, disorganized thought, hostility/excitement, and anxiety/depression were found to significantly correlate with poor functioning. Severe illness and negative symptoms are the main predictors of greater impairment of socially useful activities, personal and social relationships, and self-care. Further prospective studies in other settings, which would include an increased number of variables such as neurocognitive function and social support, are warranted.

Relative contributions of negative symptoms, insight, and coping strategies to quality of life in stable schizophrenia

The purpose of this cross-sectional study was to examine the relative contributions of negative symptomatology, insight, and coping to quality of life (QOL) in a sample of 92 consecutive outpatients with stable schizophrenia referring to the Department of Neuroscience, Psychiatric Section, University of Turin, Struttura Semplice di Coordinamento a Valenza Dipartimentale (SSCVD), Department of Mental Health ASL TO1, Molinette, Italy, in the period between July 2009 and July 2011. In order to assess the specific effect of negative symptoms on QOL and the possible mediating role of insight and coping, two mediation hypotheses were tested, using multiple regression analyses specified by Baron and Kenny (1986). Our findings suggest that (a) higher negative symptoms predict a worse Quality of Life Scale (QLS) intrapsychic foundations (IF) subscale score; (b) attribution of symptoms and coping-social diversion have a direct and positive association with QLS-IF; (c) patients high in negative symptoms are less likely to use attribution of symptoms and coping-social diversion; and (d) attribution of symptoms and coping-social diversion act as partial mediators in the negative symptoms-QOL relationship. The prediction model accounts for 45.3% of the variance of the QLS-IF subscale score in our sample. In conclusion, our results suggest that insight and coping-social diversion substantially contribute to QOL in patients with higher negative symptoms. These factors are potentially modifiable from specific therapeutic interventions, which can produce considerable improvements in the QOL of this population.

Long-term efficacy and safety of blonanserin in patients with first-episode schizophrenia: a 1-year open-label trial

AIMS

The purpose of this study was to evaluate the long-term effectiveness and safety of blonanserin, a second-generation antipsychotic drug developed in Japan, in patients with first-episode schizophrenia.

METHODS

Twenty-three antipsychotic-naïve patients with first-episode schizophrenia were treated within an open-label, 1-year, prospective trial of blonanserin (2-24 mg/day). Clinical evaluations were conducted at baseline and 2, 6, and 12 months after the start of treatment. The main outcome measures were changes in subjective well-being and subjective quality of life, as assessed by the Subjective Well-being under Neuroleptic treatment scale Short form-Japanese version and the Schizophrenia Quality of Life Scale-Japanese version, respectively. Secondary outcome measures included the Positive and Negative Syndrome Scale, the Brief Assessment of Cognition in Schizophrenia-Japanese version, laboratory tests, bodyweight, and extrapyramidal symptoms.

RESULTS

Fourteen patients (60.9%) remained on the study at 1 year. In the intention-to-treat analysis, significant improvements were observed in several subscales on the Subjective Well-being under Neuroleptic treatment scale Short form-Japanese version, the Schizophrenia Quality of Life Scale-Japanese version, and the Brief Assessment of Cognition in Schizophrenia-Japanese version, and in all factor scores on the Positive and Negative Syndrome Scale. Improvement in depressive symptoms with blonanserin treatment was positively correlated with improvements in subjective well-being and subjective quality of life, as well as verbal memory. No significant changes were noted for any safety measure during the 1-year study period.

CONCLUSIONS

Blonanserin was well tolerated and effective for the treatment of first-episode schizophrenia in terms of subjective wellness, cognition, and a wide range of pathological symptoms. Further large-scale studies are warranted to confirm our findings.

Duration of untreated psychosis as predictor of long-term outcome in schizophrenia: systematic review and meta-analysis

BACKGROUND

Duration of untreated psychosis (DUP) is one of the few potentially modifiable predictors of outcomes of schizophrenia. Long DUP as a predictor of poor short-term outcome has been addressed in previous meta-analyses, but the long-term effects of DUP remain unclear.

AIMS

To analyse the associations between DUP and long-term outcomes of schizophrenia.

METHOD

A systematic literature search was performed using seven electronic databases and manual searches. Random effects weighted meta-analysis with correlation coefficients was used to pool the results.

RESULTS

We identified 3493 unique publications, from which 33 samples met our predefined selection criteria. Long DUP correlated statistically significantly with poor general symptomatic outcome, more severe positive and negative symptoms, lesser likelihood of remission and poor social functioning and global outcome (correlations 0.13-0.18). Long DUP was not associated with employment, quality of life or hospital treatment.

CONCLUSIONS

The small but mostly consistent correlation between long DUP and poor outcome indicates that early intervention in psychosis may have at least subtle positive effects on the long-term course of illness.

Determinants of subjective health-related quality of life (HRQoL) for patients with schizophrenia

PURPOSE

To identify the determinants of schizophrenia-specific HRQoL levels, five types of factors (i.e., sociodemographic, clinical, psychopathological, neurocognitive, and psychosocial factors) were simultaneously investigated in the same cross-sectional sample.

METHODS

A total of 120 patients with a diagnosis of schizophrenia but not spectrum conditions were recruited by convenience sampling. Subjective HRQoL levels were measured using the disease-specific S-QoL-C. After sociodemographic and clinical data were collected, psychopathological data were self-rated with the Beck Depression Inventory-II (BDI-II) and were assessed with the Positive and Negative Syndrome Scale (PANSS) by professionally trained raters. Two neurocognitive assessments were conducted by licensed occupational therapists (OTs). Psychosocial factors were assessed using self-reports measures, including the, General Self-Efficacy Scale (GSES), Rosenberg Self-Esteem Scale (RSES), and Social Impact Scale (SIS). All measures were administered in random order. OTs, PANSS raters, and participants were blinded to score computation, and multiple hierarchical regression with the stepwise method was conducted.

RESULTS

The S-QoL-C scores were most strongly affected by psychosocial factors and the psychopathological factors, followed by clinical and sociodemographic factors. Total scores on the BDI-II had the largest contributions to S-QoL-C index scores and seven of eight S-QoL-C subscales. In addition, the GSES, RSES, and SIS showed effects across the S-QoL-C subscales. The BDI-II, GSES, and RSES all influenced the S-QoL-C index scores, in addition to the number of hospitalizations.

CONCLUSION

Psychosocial factors and psychopathological factors measured by the BDI-II had the greatest impact on schizophrenia-specific HRQoL levels. Psychiatric treatment programs focusing on psychosocial status and depressive symptoms can improve schizophrenia-specific HRQoL levels.

Predicting 10-year quality-of-life outcomes of patients with schizophrenia and schizoaffective disorders

AIMS

This study aimed to determine predictors for 10-year good versus poor perceived general quality of life (QOL) outcomes from baseline variables in people with schizophrenia and schizoaffective disorder.

METHODS

We compared patients with poor versus good 10-year QOL outcomes using baseline clinical, personality-related variables, demographic and background characteristics. Logistic regression analysis was used for predicting the 10-year QOL outcomes from baseline data. One-hundred-eight patients completed the Quality-of-Life Enjoyment and Life Satisfaction Questionnaire, the Positive and Negative Syndromes Scale (PANSS), the Talbieh Brief Distress Inventory, and psychosocial questionnaires at baseline and 10 years later.

RESULTS

Logistic regression revealed six predictors of QOL outcomes: paranoid ideations (odds ratio [OR] 3.1), PANSS general psychopathology (OR 1.1), obsessiveness (OR 0.84), hostility (OR 0.4), PANSS positive scale scores (OR 0.4), and general QOL index (OR 0.4). This model classified 80.6% of the sample with good sensitivity (87% correctly identified 'poor outcome'), and specificity (71% correctly identified 'good outcome').

CONCLUSION

This study provides a pattern of baseline predictors for long-term QOL outcomes. Identified predictors are factors that can potentially be ameliorated, and thereby enhance the QOL of people with schizophrenia and schizoaffective disorder.

Comparison of generic and disease-specific measures of quality of life in first-episode psychosis

BACKGROUND

Quality of life (QOL) is now recognised as an important measure of outcome that could potentially influence clinical decision-making for those with a first-episode psychosis (FEP). A number of QOL instruments are available however; many differ in their conceptual orientation which may have serious implications for the outcome of QOL studies, interpretation of findings and clinical utility. We aimed to compare two commonly used tools representing both generic and disease-specific constructs to examine whether both tools appraise the same underlying QOL traits and also whether disease-specific tools retain their psychometric properties when used in FEP groups.

METHODS

We assessed 159 consecutive individuals presenting with FEP in a defined catchment area with two commonly used QOL tools and examined the findings using the multi-trait multi-method matrix.

RESULTS

Similarly named domains of QOL between both tools (Psychological Wellbeing, Physical Health, Social Relations) showed good convergent validity using confirmatory factor analysis. However, discriminant validity was not established given that domains loading onto their indicated latent factors were more strongly correlated with their non-corresponding latent factors.

CONCLUSIONS

A major consideration in undertaking the present study was to assess the extent to which the outcome of QOL studies in FEP were valid and that systematic error did not provide another plausible explanation for findings. Establishing convergent validity demonstrates that either tool could be used satisfactorily to measure the QOL construct identified however; we did not establish discriminant validity. Doing so would have demonstrated that QOL domains are substantively different in that they contain some unique piece of information determining clinical utility. These findings are important for our understanding of multi-dimensional models of QOL.

Improved quality of life over one year is associated with improved adherence in patients with schizophrenia

AIM

Quality of life (QoL) is increasingly considered an important outcome in health research. We wished to explore the determinants of change in QoL in patients with schizophrenia over the course of a one-year RCT.

METHODS

Predictors of change in observer-rated QoL (Quality of Life Scale: QLS) were assessed in 363 patients with schizophrenia during the CUtLASS clinical trial.

RESULTS

Change in QLS score over the course of a year correlated with change in psychotic and depressive symptoms and treatment adherence. Linear regression showed that improvement in QoL was predicted by reduction in negative and depressive symptoms and improvement in adherence rating. These three change scores together explained 38% of the variance in QLS change. Exploration of the direction of any possible causal effect, using TETRAD, indicated that improved adherence leads to improved QoL, and that change in depression also leads to QoL change. The relationship between QoL and negative symptoms suggests that greater social activity (reflected as better QoL scores) improves negative symptoms. Such a direct relationship between treatment adherence and QoL has not been reported before.

CONCLUSION

Improving adherence to medication would appear to be a key approach to improving measured quality of life in people with schizophrenia.

Social dysfunction in first-episode psychosis and relations to neurocognition, duration of untreated psychosis and clinical symptoms

Signs of social dysfunction are present early in the course of psychotic disorders. There is a lack of knowledge about how premorbid function, illness history, psychotic symptoms and neurocognitive characteristics are related to social function in patients with first episode psychosis (FEP). The relationship between these factors could provide important information about the psychopathology underlying social dysfunction and have implications for future prevention and treatment efforts. Our objective is to identify early predictors of social functioning in patients with FEP. We examined 166 patients and 166 age- and gender-matched healthy controls (HC). We used a validated and comprehensive measure of social functioning (the Social Functioning Scale), a comprehensive neurocognitive test battery, in addition to measures of psychotic symptoms, duration of untreated psychosis (DUP) and premorbid adjustment (the Premorbid Adjustment Scale). Lower childhood level of social adjustment and lower psychomotor speed had the strongest influence across measures of social functioning while symptoms and DUP had a weaker influence. The main result of the current study is that premorbid social adjustment and psychomotor speed had the strongest association with measures of social functioning in patients with FEP.

Duration of untreated psychosis and negative symptoms--a systematic review and meta-analysis of individual patient data

BACKGROUND

Longer duration of untreated psychosis (DUP) is associated with poorer outcome in terms of positive symptoms, relapse rate, and time to remission. In contrast, the association with negative symptoms is less consistent.

AIMS

The study had three aims. First, to arrive at a more precise estimate of the correlation between DUP and negative symptoms than previous reviews, by substantially increasing the amount of available data. Second, to see whether the strength of this correlation attenuated over longer follow-up intervals. Third, to determine whether there is a relationship between DUP and changes in negative symptoms.

METHOD

Relevant databases were searched for studies published between December 1992 and March 2009 that reported data on DUP and negative symptoms. We obtained individual patient data where possible and calculated summary correlations between DUP and negative symptoms for each study at baseline, short and long-term follow-up. We used multilevel regression analysis to examine whether the effect of DUP on negative symptoms was the greatest in the early stages of illness.

RESULTS

We included 28 non-overlapping studies from the 402 papers detected by the search strategy. After contacting the authors we obtained individual patient data from 16 of these studies involving 3339 participants. The mean DUP was 61.4 weeks (SD=132.7, median DUP=12.0). Shorter DUP was significantly associated with less severe negative symptoms at baseline and also at short (1-2 years) and longer term follow-up (5-8 years) (r=0.117, 0.180 and 0.202 respectively, p<0.001). The relationship between improvement in negative symptoms and DUP was found to be non-linear: people with a DUP shorter than 9 months showed substantially greater negative symptom reduction than those with a DUP of greater than 9 months.

CONCLUSIONS

Shorter DUP is associated with less severe negative symptoms at short and long-term follow up, especially when the DUP is less than 9 months. Since there is no effective treatment for negative symptoms, reducing DUP to less than 9 months may be the best way to ameliorate them.

Measuring quality of life in patients with schizophrenia: an update

In 1997, we published a review in PharmacoEconomics about quality of life (QOL) measurement in patients with schizophrenia. The objective of this article is to provide an update, as well as to revisit the development of the construct of QOL and its measurement as applied to schizophrenia. Since our previous article, there has been significant growth in the number of publications about QOL in schizophrenia. Unfortunately, alongside this significant increase in research interest, a number of concerns have also risen about the limitations and lack of impact the concept of QOL has on clinical care and health-policy decision making. A number of concerns previously outlined (such as lack of consensus on a uniform definition of QOL) continue to be an issue. However, we believe that a uniform definition may not be possible, and instead, it may be preferable to have several definitions, which may enrich the concept and broaden its usefulness. Some of the scales we reviewed in 1997 continue to be in use, while others are now rarely or never used. New scales with better psychometrics have been introduced, but most are without theoretical or conceptual foundation. On the other hand, the field of scaling in general has been changing over the past few years and is moving towards a new approach for scale development, based on item response theory, item banks and computer adaptive testing. Unfortunately, this has not extended to QOL in schizophrenia. There continues to be a dearth of theoretical and conceptual models for QOL in schizophrenia, which seems to create the perception that the construct lacks a good theoretical and scientific foundation. One of the major gaps identified in this review is the recognized lack of impact of QOL measurements on clinical management or policy decision making. The majority of publications continue to focus on measurement rather than what to do with the data. The lack of strategies to integrate QOL data in clinical care, as well as the failure to contribute to policy decisions, particularly in cost analysis or resource allocations, has created the perception that the construct of QOL in schizophrenia is not that useful. It is evident that, for QOL in schizophrenia to regain its promise, researchers must take the ultimate next step beyond measurement: to develop credible strategies for integrating QOL data in clinical practice. Additionally, more focused research is needed to demonstrate the role of QOL, not only as an outcome in itself but also as a contributor to other outcomes, such as adherence to medications, more satisfaction, less resource utilization and so on. Since self-appraisal of QOL does not happen in a vacuum but relates to the total human experience in all its biological, psychosocial and environmental aspects, particular attention must also be focused on important neurobiological dimensions such as affect and cognition. Both are significantly affected by the illness itself and its treatment.

Relationship of symptomatic remission with quality of life and functionality in patients with schizophrenia

OBJECTIVE

The aim of this study was to investigate the relationship between remission and quality of life (QoL) of patients with schizophrenia.

METHOD

Quality of life was investigated with the Quality-of-Life Scale, the Personal and Social Performance Scale (PSP), and the Evaluation of Functional Remission Scale in 102 outpatients with schizophrenia. Positive and Negative Syndrome Scale and Calgary Depression Scale for Schizophrenia (CDSS) were used to assess symptom severity. Remission was defined based on the Andreasen et al criteria (2005).

RESULTS

The remission group had higher levels of QoL and functionality as measured by the Quality-of-Life Scale (P = .001), PSP (P = .001), and Evaluation of Functional Remission Scale (P = .001). The remission group also had higher employment rates, lower smoking rates, and less depressive symptoms. We found that negative (P = .001) and positive symptoms of the Positive and Negative Syndrome Scale (P = .05) and CDSS score (P = .005) independently contributed to PSP score in a linear regression analysis. Years of education and positive symptoms were related to CDSS score. All of the 3 scales that we used to assess QoL and functionality were highly correlated with each other. In addition, the opinions of patients or relatives/partners about functionality of the patient was highly correlated with all of the scales.

CONCLUSION

We found significant differences between patients with schizophrenia with and without remission for QoL and functionality. Relative/partner's evaluation of functional status provides a reliable measure of QoL as well.

Subjective quality of life in patients with chronic schizophrenia: relationships between psychosocial and clinical characteristics

BACKGROUND

Using the theoretical framework of quality of life (QOL), many studies have demonstrated that the beliefs individuals hold about their QOL are important in predicting health outcomes. This study tested the Taiwanese version of the World Health Organization Quality of Life-Brief (WHOQOL-BREF) assessment in schizophrenia patients. The WHOQOL-BREF is a cross-cultural and widely used measure for assessing health-related QOL. This brief version of the questionnaire derived from the concepts included in the 100-item WHOQOL questionnaire was adapted for use in Taiwan.

METHODS

In the current cross-sectional study, 104 patients who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for schizophrenia or schizoaffective disorder according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria were recruited and independently interviewed using the Taiwanese version of the WHOQOL-BREF. Patients were also examined using various other scales assessing insight, symptom severity, general psychopathology, and antipsychotic-induced side effects. In addition, we analyzed demographic data, clinical variables, and several self-rating scales as correlates of the Taiwanese version of the WHOQOL-BREF.

RESULTS

As predicted, age, onset of illness, insight measures, symptom severity, general psychopathology, and antipsychotic-induced side effects were all significantly related to the QOL scores. Multiple regression analyses revealed that depressive symptoms, antipsychotic-induced parkinsonism side effects, hopelessness, and age at illness onset were the 4 strongest predictors of subjective QOL in schizophrenia patients. These variables accounted for 39.2% of the total variance of this QOL model.

CONCLUSIONS

The results suggest that the WHOQOL-BREF is a promising model for mental assessing health problems in schizophrenia patients. Furthermore, the present findings highlight the importance of understanding the complex nature of the concept of QOL. Our study also supports the belief that different domains of QOL are likely to have different predictors.

The development of subjective quality of life over the first 2 years in first-episode psychosis

The main aim of this study was to examine changes in subjective quality of life (general s-QoL) in patients with first-episode psychosis from baseline to 2 years follow-up. A total of 201 of 252 patients had full quality of life assessment at both baseline and at 2 years. Repeated measure analyses of variance were done to evaluate the development over time, and multiple linear regression analyses to evaluate predictors of change. These patients with a first-episode psychosis showed a significant improvement in general s-QoL during the first 2 years of treatment. Improvements in general s-QoL were associated with increase in excitative symptoms and with improvements in depressive symptoms, global functioning, level of daily activities, level of social activities, and perceived general health.

Mastery and stigma in predicting the subjective quality of life of patients with schizophrenia in Taiwan

A total of 199 outpatients with schizophrenia are assessed in this study for their sense of mastery, stigma, social support, symptom severity, and quality of life (QOL), with path models being used to test the direct and indirect effects of these factors on the physical, psychological, social, and environmental QOL domains. Symptoms, stigma, mastery, and social support are found to be key direct predictors for all 4 QOL domains, with mastery having the greatest direct effect on QOL, whereas stigma has the greatest indirect effect, although mediated by mastery and social support. Such results imply that in nonwestern cultures, mastery and stigma are still crucial factors affecting the QOL of patients with schizophrenia. Our results highlight the importance of enhancing the mastery of such patients and reducing the associated stigma when designing treatment programs. To enhance the QOL of patients with schizophrenia, interventions which can optimize the meaningful use of time may well enhance the mastery of these patients, whereas strategies aimed at improving their ability to cope with perceived stigma, at both individual and community levels, may help to reduce the detrimental effects.

Social functioning in urban, predominantly African American, socially disadvantaged patients with first-episode nonaffective psychosis

BACKGROUND

Social functioning impairments develop and accumulate even prior to initial treatment-seeking for first-episode psychosis. This study, the first to examine social functioning in low-income, urban, predominantly African American first-episode patients: (1) assesses the internal consistency of Social Functioning Scale (SFS) subscales in this relatively unique sample; (2) identifies demographic and clinical variables that may be predictive of poor social functioning in this particular population; and (3) assesses changes in SFS scores in a subsample re-assessed six months after initial hospitalization.

METHODS

109 participants (age, 23.1+/-4.7years; 76.1% male; 89.9% African American) hospitalized for a first episode of nonaffective psychosis in an urban, public-sector setting were administered the SFS along with other clinical research instruments. 34 (31.2%) returned for a follow-up clinical research assessment six months after baseline assessment. Associations between the variables of interest were analyzed utilizing independent samples Student's t-tests and Pearson correlations.

RESULTS

Associations were observed between social functioning domains and negative symptoms (r=-.21--.32, p<.05), depressive symptoms (r=-.20--.23, p<.05), and general psychopathology symptoms (r=-.23--.24, p<.05). No significant differences were found in SFS subscale scores between baseline and six-month follow-up.

CONCLUSIONS

Deficits in social functioning are meaningfully related to several domains of symptoms, and such deficits may be relatively stable in the early course of psychotic disorders. Such findings may inform development of psychosocial interventions targeting social functioning in first-episode patients.

Psychological well-being among individuals with first-episode psychosis

AIM

Psychological well-being is a subjective component of quality of life (QOL) that has been previously unexplored in individuals recovering from an initial psychotic episode. This study examined predictors of psychological well-being among individuals with first-episode psychosis (FEP) and compared it to a non-clinical college-aged comparison group.

METHODS

The Scales of Psychological Well-Being (SPWB) Environmental Mastery and Purpose in Life subscales were administered to both clinical (n = 41) and control (n = 39) participants. Clinical participants were also assessed on symptom measures and QOL, and all participants completed a measure of perceived social support. Multiple regression analyses were carried out to determine predictors of well-being in the FEP sample.

RESULTS

SPWB scores were significantly lower for the FEP group in comparison to the control group. Additionally, greater perceived social support and lower levels of depression were found to be significant predictors of psychological well-being in the clinical sample, whereas gender and negative symptoms were not significant predictors.

CONCLUSIONS

These results suggest that the development of a psychotic episode is associated with decreased subjective well-being, and that depression and social support may play an important role in this aspect of an individual's recovery. Additionally, the SPWB appear to be tapping into an important construct that has been relatively unexamined in first-episode research and may have potential utility in clinical practice and future treatment development.

Impaired parent-reported quality of life in treatment-seeking children with obesity is mediated by high levels of psychopathology

PURPOSE

The purpose of the current study was to explore psychopathology as a mediator of quality of life (QOL) in children and adolescents with obesity. The notion that psychopathology and QOL are two distinct constructs was also tested.

METHODS

A sample of treatment-seeking children and adolescents with obesity (n = 185, average age = 11.5, mean BMI SDS = 3.03) was matched to a community sample of children (n = 799, average age = 11.5). Both self- and parent-reported measures of QOL (KINDL-R) and psychopathology (CBCL/YSR) was completed.

RESULTS

Parent-reported QOL was impaired, and both self-reported and parent-reported psychopathology was elevated in children and adolescents with obesity. Psychopathology accounted for all the variance of the effect of obesity on parent-reported QOL. The distinction between QOL and psychopathology was supported through confirmatory factor analysis.

CONCLUSION

Impaired parent-reported QOL in children and adolescents with obesity was attributable to their elevated levels of psychopathology.
