Mood state and quality of sleep in cancer pain patients: a comparison to chronic daily headache

Pilot study of tai chi and qigong on body composition, sleep, and emotional eating in midlife/older women

Weight gain and related adverse changes in body composition are prevalent among midlife and older women and contribute to chronic disease (e.g., type 2 diabetes, hypertension, depression). Tai Chi (TC) and Qigong (QG), forms of Meditative Movement, demonstrate improved physical/psychological symptoms and body composition. Using a standardized TC/QG protocol, we explored pre/post intervention differences in percent body fat and factors related to body composition in midlife/older women. In the context of a single-group pilot study, females ages 45-75 (N = 51) enrolled in an 8-week TC/QG intervention. Primary outcome measures of body composition, sleep quality, emotional eating and select secondary outcome psycho-emotional factors (perceived stress, mood state, mindfulness, self-compassion, body awareness) were collected. Change in percent body fat did not reach statistical significance (p = .30, M =  0.35, 95% CI [- 0.32, 1.0]). Sleep quality improved significantly, p = .04, M = - 0.88, 95% CI [-1.71, - 0.04]. Emotional eating changed in the expected direction, but not significantly, p = .08, M =  -0.16, 95% CI [-0.34, 0.02]. Significant differences were found in body awareness, p = .01, M =  0.36, 95% CI [0.08, 0.63] and perceived stress, p = .05, M =  -2.36, 95% CI [-4.76, 0.04]. Preliminary results are promising as results showed improvements in factors related to healthy body composition. Refined research is needed to understand if/how TC/QG may improve body composition among midlife and older women.

Effect of neuromuscular electrical stimulation for fatigue management in patients with advanced laryngeal cancer receiving chemoradiotherapy

This study retrospectively investigated the effect of neuromuscular electrical stimulation (NMES) for fatigue management in patients with advanced laryngeal cancer (ALC) receiving chemoradiotherapy.A total of 60 eligible patients with ALC receiving chemoradiotherapy were included. These patients were assigned equally to a treatment group and a control group. Patients in the treatment group received NMES therapy and were treated for a total of 8 weeks, while the patients in the control group did not receive NMES therapy. The primary outcome was fatigue, measured by the multidimensional fatigue inventory (MFI). The secondary outcomes included anxiety and depression, measured by the Hospital Anxiety and Depression Scale (HADS), and sleep quality, measured by the Pittsburgh Sleep Quality Index (PSQI). All outcomes were evaluated before and after 8-week NMES treatmentAfter 8-week NMES treatment, the patients in the treatment group did not exert better effect than patients in the control group in fatigue relief, measured by the MFI score, anxiety and depression decrease, assessed by HADS, and sleep quality improvement, evaluated by PSQI.The results of this study demonstrate that NMES may not benefit for fatigue relief in patients with ALC receiving chemoradiotherapy. Future studies should still focus on this topic and warrant these results.

Effect of therapeutic care for treating fatigue in patients with breast cancer receiving chemotherapy

BACKGROUND

This study aimed to evaluate the effect of therapeutic care (TC) for fatigue in breast cancer patients receiving chemotherapy.

METHODS

A total of 48 breast cancer patients receiving chemotherapy were randomly divided into the intervention group and the control group, with 24 patients in each group. The patients in the intervention group were treated with TC, while the participants in the control group received the sham intervention. The interventions in both groups were for 30 min/d, 3 days weekly for 12 weeks. The primary outcome of fatigue was measured by the multidimensional fatigue inventory (MFI). The secondary outcomes were measured by the Hospital Anxiety and Depression Scale (HADS) and Pittsburgh Sleep Quality Index (PSQI). All outcomes were assessed before and after 6 and 12 weeks of the intervention.

RESULTS

The intervention with TC showed greater efficacy than sham TC in decreasing the MFI score after week 6 (P < .05) and week 12 (P < .01) of treatment. Significant differences were also found in the HADS and PSQI between the 2 groups after 12 weeks of treatment (P < .01).

CONCLUSION

This study demonstrated that TC might decrease fatigue and relieve the anxiety and depression of breast cancer patients receiving chemotherapy.

Acupuncture and Related Therapies for Symptom Management in Palliative Cancer Care: Systematic Review and Meta-Analysis

Available systematic reviews showed uncertainty on the effectiveness of using acupuncture and related therapies for palliative cancer care. The aim of this systematic review and meta-analysis was to summarize current best evidence on acupuncture and related therapies for palliative cancer care. Five international and 3 Chinese databases were searched. Randomized controlled trials (RCTs) comparing acupuncture and related therapies with conventional or sham treatments were considered. Primary outcomes included fatigue, paresthesia and dysesthesias, chronic pain, anorexia, insomnia, limb edema, constipation, and health-related quality of life, of which effective conventional interventions are limited. Thirteen RCTs were included. Compared with conventional interventions, meta-analysis demonstrated that acupuncture and related therapies significantly reduced pain (2 studies, n = 175, pooled weighted mean difference: -0.76, 95% confidence interval: -0.14 to -0.39) among patients with liver or gastric cancer. Combined use of acupuncture and related therapies and Chinese herbal medicine improved quality of life in patients with gastrointestinal cancer (2 studies, n = 111, pooled standard mean difference: 0.75, 95% confidence interval: 0.36-1.13). Acupressure showed significant efficacy in reducing fatigue in lung cancer patients when compared with sham acupressure. Adverse events for acupuncture and related therapies were infrequent and mild. Acupuncture and related therapies are effective in reducing pain, fatigue, and in improving quality of life when compared with conventional intervention alone among cancer patients. Limitations on current evidence body imply that they should be used as a complement, rather than an alternative, to conventional care. Effectiveness of acupuncture and related therapies for managing anorexia, reducing constipation, paresthesia and dysesthesia, insomnia, and limb edema in cancer patients is uncertain, warranting future RCTs in these areas.

Effects of a selective educational system on fatigue, sleep problems, daytime sleepiness, and depression among senior high school adolescents in Taiwan

OBJECTIVE

The aim of the study reported here was to clarify the effects of academic pressure on fatigue, sleep problems, daytime sleepiness, and depression among senior high school adolescents in Taiwan.

METHODS

This cross-sectional study enrolled 757 senior high school adolescents who were classified into four groups: Grade 1 (n=261), Grade 2 (n=228), Grade 3T (n=199; Grade 3 students who had another college entrance test to take), and Grade 3S (n=69; Grade 3 students who had succeeded in their college application). Fatigue, sleep quality, daytime sleepiness, and depression were assessed using the Chinese version of the Multidimensional Fatigue Symptom Inventory - Short Form, Pittsburgh Sleep Quality Index-Taiwan Form, the Chinese version of the Epworth Sleepiness Scale, and the Chinese version of the Beck Depression Inventory(®)-II (BDI-II), respectively.

RESULTS

Physical, emotional, and mental fatigue scores were all higher in higher-grade groups. The Grade 3T (test) students had the worst fatigue severity, and the Grade 3S (success) students had the least fatigue severity. More than half of the students (60.9%) went to bed after 12 am, and they had on average 6.0 hours of sleep per night. More than 30% of the students in Grade 2 (37.3%) and Grades 3T/S (30.2%/30.4%) possibly had daily sleepiness problems. The students in Grade 3T had the worst BDI-II score (13.27±9.24), and the Grade 3S students had a much lower BDI-II score (7.91±6.13).

CONCLUSION

Relatively high proportions of fatigue, sleep problems, daytime sleepiness, and depression among senior high school adolescents were found in our study. The severities of fatigue, sleep problems, and depression were significantly diminished in the group under less academic stress (Grade 3S). Our findings may increase the understanding of the mental health of senior high school students under academic pressure in Taiwan. Further large sample size and population-based study should be done for better understanding about this topic.

Systematic review of sleep disorders in cancer patients: can the prevalence of sleep disorders be ascertained?

Although sleep is vital to all human functioning and poor sleep is a known problem in cancer, it is unclear whether the overall prevalence of the various types of sleep disorders in cancer is known. The purpose of this systematic literature review was to evaluate if the prevalence of sleep disorders could be ascertained from the current body of literature regarding sleep in cancer. This was a critical and systematic review of peer-reviewed, English-language, original articles published from 1980 through 15 October 2013, identified using electronic search engines, a set of key words, and prespecified inclusion and exclusion criteria. Information from 254 full-text, English-language articles was abstracted onto a paper checklist by one reviewer, with a second reviewer randomly verifying 50% (k = 99%). All abstracted data were entered into an electronic database, verified for accuracy, and analyzed using descriptive statistics and frequencies in SPSS (v.20) (North Castle, NY). Studies of sleep and cancer focus on specific types of symptoms of poor sleep, and there are no published prevalence studies that focus on underlying sleep disorders. Challenging the current paradigm of the way sleep is studied in cancer could produce better clinical screening tools for use in oncology clinics leading to better triaging of patients with sleep complaints to sleep specialists, and overall improvement in sleep quality.

Selected neurophysiological, psychological, and behavioral influences on subjective sleep quality in nurses: a structure equation model

Few studies have examined relationships among neurophysiological, psychological, and behavioral factors with regard to their effects on sleep quality. We used a structure equation model to investigate behavioral and psychological factors that influence neurophysiological regulation of sleep in shift workers. Using a cross-sectional study design, we tested the model with a sample of 338 female nurses working rotating shifts at an urban regional hospital. The Morningness-Eveningness Questionnaire (MEQ) and short-form Menstrual Distress Questionnaire (MDQ) were used to measure neurophysiological factors involved in morningness-eveningness and menstrual distress. The Sleep Hygiene Awareness and Practice Scale (SHAPS) and Profile of Mood States Short Form (POMS-SF) were completed to measure behavioral factors of sleep hygiene practices and psychological factors of mood states. In addition, the Pittsburgh Sleep Quality Index (PSQI) measured participant's self-reported sleep quality. The results revealed that sleep hygiene practices and mood states mediated the effects of morningness-eveningness and menstrual distress on sleep quality. Our findings provide support for developing interventions to enhance sleep hygiene and maintain positive mood states to reduce the influence of neurophysiological factors on sleep quality among shift workers.

Rest/activity rhythm is related to the coexistence of pain and sleep disturbance among advanced cancer patients with pain

PURPOSE

This study aimed to explore the relationships among pain, sleep disturbance, and circadian rhythms in advanced cancer patients.

METHODS

This cross-sectional study was conducted in 68 cancer patients from the oncology inpatient unit of a teaching hospital. Their demographic and medical characteristics, questionnaire surveys, including Brief Pain Inventory-Chinese version and Pittsburgh Sleep Quality Index Taiwanese version, and sleep logs and actigraphic recordings in consecutive 3 days and nights were collected and analyzed.

RESULTS

The mean (SD) scores for autocorrelation coefficient at 24 h (r24) and dichotomy index (I<O) were 0.19 (0.16) and 85.29 % (0.13 %), respectively, indicating dampened circadian rhythms in participants. The mean (SD) worst pain score was 5.47 (2.70). The sleep quality global score ranged 4 ∼ 19 with a mean (SD) of 11.19 (4.05). The worst pain levels, the Pittsburgh Sleep Quality Index (PSQI) global score, and most sleep parameters measured by actigraphy were significantly correlated with r24 and I<O. The worst pain score was significantly correlated with the PSQI global score (r = 0.69, p < 0.01). The Goodman version of the Sobel test further demonstrated that 45.77 % of the total effect was mediated by pain intensity (t = 2.76, p = 0.005). Pain was a complete mediator between circadian rhythms and sleep quality.

CONCLUSIONS

The rest/activity rhythm influences the coexisting pain and sleep disturbances. Pain functions as a complete mediator in their relationship. Interventions that improve rest/activity rhythms may improve the management of pain and sleep disturbances in cancer patients.

A comparison between acupuncture versus zolpidem in the treatment of primary insomnia

BACKGROUND

To determine the relative efficacy of acupuncture and zolpidem in the treatment of primary insomnia, we administered a sleep quality scale to thirty-three patients with primary insomnia randomly chosen to receive one of the two therapies at a psychosomatic clinic.

METHODS

A study in the psychosomatic clinic at a teaching hospital in southern Taiwan from November 2007 to November 2008. The 19 patients in acupuncture group underwent one acupuncture session a week. The 14 patients in the control group took zolpidem 1# (10mg) every night. Members of both groups returned to our clinic once a week for four weeks. The main outcome measure was the Pittsburgh Sleep Quality Index (PSQI).

RESULTS

Both groups were found to have improved significantly. Using generalized estimating equation analysis to test the variance with group and time as factors, we found both groups improved over time at a similar rate (p=0.79). In regression analysis, setting the fourth total PSQI score to zero, the baseline PSQI score was 4.13 (p<0.001), the second score 1.32 (p=0.005), and the third 1.49 (p=0.03); men had a higher PSQI score 1.56 than women (p=0.02); the increasing age of one year would have lower PSQI score 0.08 (p<0.001) and increasing educational level of one year which would decrease PSQI score 0.25 (p=0.007).

CONCLUSIONS

Acupuncture might be used as an alternative strategy compared to zolpidem for the treatment of primary insomnia.

Comparison of differences and determinants between presence and absence of sleep disturbance in hepatocellular carcinoma patients

BACKGROUND

Hepatocellular carcinoma patients often experience sleep disturbance after undergoing transcatheter arterial chemoembolization (TACE).

OBJECTIVE

The objectives of this study were to (1) examine and compare symptom distress, depression, and sleep quality in hepatocellular carcinoma patients undergoing TACE with sleep disturbance versus without sleep disturbance and (2) examine the determinants of sleep disturbance in these patients.

METHODS

Hepatocellular carcinoma patients undergoing TACE were recruited. The patients were evaluated 1 week (T1) and 1 month (T2) after receiving TACE in terms of performance status, symptom distress, depression (T1), and sleep disturbance (T2). Logistic regression was used to determine the predictive factors of sleep disturbance.

RESULTS

Patients with sleep disturbance reported significantly higher overall symptom distress and depression and lower sleep quality than patients without sleep disturbance. The 5 leading causes of symptom distress in both groups were fatigue, pain, poor appetite, chest tightness, and fever. Older age, greater symptom distress, and higher levels of depression were significantly associated with sleep disturbance.

CONCLUSIONS

The results of this study show significant associations among symptom distress, depression at baseline, and sleep problems 1 month after undergoing TACE. Clinicians should be aware of the possibility of lasting sleep disturbance in hepatocellular carcinoma patients undergoing TACE.

IMPLICATIONS FOR PRACTICE

In clinical care, symptom management, psychological consultation, and relaxation training may promote sleep quality.

Validity and reliability of the Taiwanese version of the Pittsburgh Sleep Quality Index in cancer patients

BACKGROUND

Sleep disturbance remains a common symptom among cancer patients. Assessment of sleep disturbance in cancer patients is hindered by infrequent use of standardized tools for sleep management.

OBJECTIVES

The purposes of this study were to validate the Taiwanese version of the Pittsburgh Sleep Quality Index (PSQI-T) and to determine detection cut-off points in cancer patients.

DESIGN

A cross-sectional and descriptive correlational design.

PARTICIPANTS

A sample of 205 Taiwanese patients with various cancer diagnoses.

METHODS

The survey included the Pittsburgh Sleep Quality Index-Taiwanese version, the MD Anderson Symptom Inventory-Taiwanese version, the Brief Fatigue Inventory-Taiwanese version, the seven-day sleep log, and Manual of Mental Disorders, Fourth Edition.

RESULTS

The internal consistency Cronbach's alpha for the PSQI was 0.79. Test-retest reliability was 0.91 for the global score over a 20- to 28-day interval in a sample of 16 patients. Construct validity was established by a significant relationship of the PSQI-T global score to the total symptom severity score and the fatigue severity score. Convergent validity was examined by correlating the PSQI-T scores and scores of the DSM-IV and scores on the seven-day sleep log. Known-group validity was established by comparing PSQI-T scores for patients having low fatigue levels and those having high fatigue levels. Receiver-operating characteristic (ROC) curves were used to determine the detection cut-off points.

CONCLUSIONS

We found that a PSQI-T global score of 8 generates the best sensitivity and specificity for measuring sleep disturbance in cancer patients. The PSQI-T is a reliable, valid, and sensitive instrument for measuring sleep quality among Taiwanese cancer patients.

Sleep-wake circadian activity rhythm parameters and fatigue in oncology patients before the initiation of radiation therapy

BACKGROUND

Little is known about the relationships between sleep parameters and fatigue in patients at the initiation of radiation therapy (RT).

OBJECTIVES

The objectives of this study were to describe values for nocturnal sleep/rest, daytime wake/activity, and circadian activity rhythm parameters measured using actigraphy and to evaluate the relationships between these objective parameters and subjective ratings of sleep disturbance and fatigue severity, in a sample of patients at the initiation of RT.

METHODS

Patients (n = 185) with breast, prostate, lung, or brain cancer completed self-report measures for sleep disturbance (ie, Pittsburgh Sleep Quality Index, General Sleep Disturbance Scale) and fatigue (Lee Fatigue Scale) and wore wrist actigraphs for a total of 48 hours prior to beginning RT. Actigraphy data were analyzed using the Cole-Kripke algorithm. Spearman rank correlations were calculated between variables.

RESULTS

Approximately 30% to 50% of patients experienced sleep disturbance, depending on whether clinically significant cutoffs for the subjective or objective measures were used to calculate occurrence rates. In addition, these patients reported moderate levels of fatigue. Only a limited number of significant correlations were found between the subjective and objective measures of sleep disturbance. Significant positive correlations were found between the subjective, but not the objective measures of sleep disturbance and fatigue.

CONCLUSIONS

A significant percentage of oncology patients experience significant disturbances in sleep-wake circadian activity rhythms at the initiation of RT. The disturbances occur in both sleep initiation and sleep maintenance.

IMPLICATIONS FOR PRACTICE

Patients need to be assessed at the initiation of RT for sleep disturbance, so appropriate treatment is initiated.

Validation of the Taiwanese version of the Athens Insomnia Scale and assessment of insomnia in Taiwanese cancer patients

CONTEXT

It is well known that insomnia is highly prevalent in cancer patients. Although various studies have used the Athens Insomnia Scale (AIS) for insomnia assessment, it has never been applied to cancer patients with insomnia.

OBJECTIVES

The purpose of this study was to establish the reliability and validity of the Taiwanese AIS version (AIS-T) and evaluate the severity of insomnia among cancer patients in Taiwan.

METHODS

Using a cross-sectional research design, 195 cancer patients (n=195) were recruited from outpatient oncology clinics.

RESULTS

Cronbach's alpha for internal consistency was 0.83, and the test-retest reliability was 0.94 over an interval of three days, based on a sample of 30 patients. Moreover, concurrent validity could be evaluated by significant correlations of the AIS-T with the Pittsburgh Sleep Quality Index-Taiwan form (PSQI-T) (r=0.82, P<0.001) and sleep efficiency measured by Actiwatch parameters (r=-0.54, P<0.001). Construct validity could be established by the Brief Fatigue Inventory-Taiwan form (r=0.56, P<0.001) and Medical Outcomes Study Short Form-36-Taiwanese version (physical component summary: r=-0.52, P<0.001; mental component summary: r=-0.53, P<0.001). The AIS-T could detect significant known-group validity from sleep quality (PSQI-T ≥ 5 or <5, respectively). The Actiwatch parameters are consistent with the results of the AIS-T, and both data sets indicate that patients experienced sleep disturbances. The prevalence of insomnia, as defined by the criteria of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, 4th ed., was 22.56%; 49.2% subjects had significant insomnia at the score ≥ 6 at AIS-T.

CONCLUSION

This study concludes that the AIS-T is a reliable and valid instrument for assessing insomnia among cancer patients in Taiwan.

The mediating effects of depression on sleep disturbance and fatigue: symptom clusters in patients with hepatocellular carcinoma

The purposes of this study were to (a) explore the relationships among sleep disturbance, fatigue, and depression and (b) test whether depression mediates the effect of sleep disturbance on fatigue in patients with hepatocellular carcinoma (HCC). A cross-sectional study was conducted with a total of 77 patients with HCC. All participants completed questionnaires that included the Brief Fatigue Inventory-Taiwan Form, the Pittsburgh Sleep Quality Index-Taiwan Form, and the depression subscale of the Taiwanese version of the Hospital Depression and Anxiety Scale. Path analysis was used to test the mediation role of depression. Fatigue, sleep disturbance, and depression are positively interrelated and co-occur in patients with HCC. Moreover, depression completely mediates the effects of sleep disturbance on fatigue. These findings suggest that depression is an important mechanism underlying the relationship between sleep disturbance and fatigue for patients with HCC. This is the first study to explore the phenomenon of symptom clustering in sleep disturbance, fatigue, and depression in patients with HCC and to investigate the mediating role of depression that underlies the relationship between sleep disturbance and fatigue. The current findings are of clinical importance because they suggest the need to consider simultaneous management of sleep disturbance, fatigue, and depression.

Improving sleep quality for cancer patients: benefits of a home-based exercise intervention

PURPOSE

1) To determine the effect of a home-based walking exercise program on the sleep quality and quality of life of cancer patients, as well as 2) to determine if enhanced sleep quality was associated with improvement in quality of life over time.

METHODS

This is a prospective, longitudinal, two-armed, randomized clinical trial. Participants were recruited from oncology outpatient clinics in two university-based medical centers and were allocated to either usual care (n = 35) or a home-based walking exercise intervention for 8 weeks (n = 36). Measurements included the Taiwanese version of the Pittsburgh Sleep Quality Index, the Medical Outcomes Study Short Form-36, the Taiwanese Version Ratings of the Perceived Exertion Scale, and a walking exercise log. This study was analyzed on an intention-to-treat basis. Effects of the walking exercise program on sleep quality and quality of life were analyzed by the generalized estimating equation method.

RESULTS

Patients in the exercise group reported significant improvements in sleep quality (beta = -3.54, p < 0.01) and the mental health dimension of quality of life (beta = 10.48, p < 0.01). Among patients who exercised, enhanced sleep quality also corresponded with reduced bodily pain (beta = 0.98, p = 0.04) and improvements over time in the mental health dimension of quality of life (beta = -3.87, p < 0.01).

CONCLUSIONS

A home-based walking exercise program can be easily incorporated into care for cancer patients who are suffering from sleep disturbances.

Barriers to pain management in a community sample of Chinese American patients with cancer

Barriers to cancer pain management can contribute to the undertreatment of cancer pain. No studies have documented barriers to cancer pain management in Chinese American patients. The purposes of this study in a community sample of Chinese Americans were to: describe their perceived barriers to cancer pain management; examine the relationships between these barriers and patients' ratings of pain intensity, pain interference with function, mood disturbances, education, and acculturation level; and determine which factors predicted barriers to cancer pain management. Fifty Chinese Americans with cancer pain completed the following instruments: Brief Pain Inventory (BPI), Karnofsky Performance Status (KPS) Scale, Barriers Questionnaire (BQ), Hospital Anxiety and Depression Scale (HADS), Suinn-Lew Asian Self-Identity Acculturation Scale (SL-ASIA), and a demographic questionnaire. The mean total BQ score was in the moderate range. The individual barriers with the highest scores were: tolerance to pain medicine; time intervals used for dosage of pain medicine; disease progression; and addiction. Significant correlations were found between the tolerance subscale and least pain (r=0.380) and the religious fatalism subscale and average pain (r=0.282). These two subscales were positively correlated with anxiety and depression levels: (tolerance: r=0.282, r=0.284, respectively; religious fatalism: r=0.358, r=0.353, respectively). The tolerance subscale was positively correlated with pain interference (r=0.374). Approximately 21% of the variance in the total BQ score was explained by patients' education level, acculturation score, level of depression, and adequacy of pain treatment. Chinese American cancer patients need to be assessed for pain and perceived barriers to cancer pain management to optimize pain management.

Theories, models, and frameworks related to sleep-wake disturbances in the context of cancer

The purpose of this article was to review theories, models, and frameworks of sleep disturbances referenced in the cancer literature. Sleep-wake disturbances in cancer are a significant problem that negatively affects quality of life. There is no previously published review of the theories, models, or frameworks used to study sleep-wake disturbances in the context of cancer. Describing existing theories or models and their application in cancer is important to advance knowledge in this area. Two theories and 9 models were identified for review. These have been used to further understand the problem of sleep-wake disturbances as a primary or secondary symptom within the cancer literature. Searches were conducted from January 1, 1970, to July 31, 2008, to find relevant articles using 4 electronic databases: MEDLINE, CINAHL, PubMed, and PsychINFO. On the basis of the search, 73 descriptive or intervention studies were identified and reviewed. Most research was atheoretical, with no identified theory, model, or framework. In studies that did use theory or models, few were applied in more than one study. Although several commonalities across models did emerge, a more comprehensive and widely used model could help guide nursing research to facilitate effective symptom management for this prominent problem in cancer.

Affective personality as cognitive-emotional presymptom profiles regulatory for self-reported health predispositions

Three studies that examined the links between affective personality, as constructed from responses to the Positive Affect (PA) and Negative Affect (NA) Scale (PANAS), and individuals' self-report of self-esteem, intrinsic motivation and Beck's Depression Inventory (BDI) depression in high school students and persons in working occupations are described. Self-report estimations of several other neuropsychiatric and psychosocial variables including, the Uppsala Sleep Inventory (USI), the Hospital Anxiety and Depression (HAD) test, Dispositional optimism, Locus of control, the Subjective Stress Experience test (SSE) and the Stress-Energy (SE) test, were also derived. Marked effects due to affective personality type upon somatic and psychological stress, anxiety and depression, self-esteem, internal and external locus of control, optimism, stress and energy, intrinsic motivation, external regulation, identified regulation, major sleep problems, problems falling asleep, and psychophysiological problems were observed; levels of self-esteem, self-motivation and BDI-depression all produced substantial effects on health and well-being. Regression analyses indicated PA was predicted by dispositional optimism (thrice), energy (thrice), and intrinsic motivation, and counter predicted by depression (twice) and stress (twice); and NA by anxiety (twice), stress (twice), psychological stress, identified regulation, BDI depression and psychophysiological problems, and counter predicted by internal locus of control and self-esteem. BDI-depression was predicted by negative affect, major sleep problems and psychophysiological problems (Study III), self-esteem by dispositional optimism and energy, and counter predicted by anxiety, depression and stress (Study I), and intrinsic motivation by dispositional optimism, energy, PA and self-esteem (Study II). These convergent findings are interpreted from a perspective of the cognitive-emotional expressions underlying behavioural or presymptomatic profiles presenting predispositions for health or ill health.
