Association between negative symptom domains and happiness in schizophrenia

Examination of internalized stigma, quality of life, and happiness in patients with schizophrenia

BACKGROUND

Happiness in patients with schizophrenia is a neglected concept that needs to be developed. Determining the relationship between internalized stigma, quality of life, and happiness, which is important for the prognosis of schizophrenia, will reveal why it is necessary to focus on activities that will increase happiness in patients with schizophrenia.

AIM

This study aimed to compare the levels of internalized stigma, quality of life, and happiness in patients with schizophrenia.

METHODS

A descriptive and correlational research design was used. The research population consisted of patients who applied to the psychiatry outpatient clinic of a hospital in eastern Turkey during the research period and were diagnosed with schizophrenia according to the DSM-5 diagnostic criteria; 87 voluntary patients who agreed to participate in the study constituted the research sample. A personal information form, the Internalized Stigma of Mental Illness Scale (ISMI), the World Health Organization Quality-of-Life Scale (WHOQOL-BREF), and the Subjective Happiness Scale (SHS) were used for data collection.

RESULTS

According to the patients' ISMI, WHOQOL-BREF-TR, and SHS scores, patients perceived internalized stigma above the moderate level in all sub-dimensions. In general, their quality of life was moderate (the highest mean score was on the national environment domain and the lowest mean score was on the social domain); the mean SHS score was 13.02 ± 5.53. There was a strong and negative correlation between the mean SHS score and the total ISMI score and a strong and positive correlation between SHS and the physical, mental, social, and national environment domains of WHOQOL-BREF-TR.

CONCLUSIONS

It was determined that the mean internal stigma score of the patients decreased and their mean quality of life score increased as their mean subjective happiness score increased. It is recommended clinical studies be carried out to increase happiness in patients with schizophrenia.

Influence of positive and negative symptoms on hedonic and eudaemonic well-being in people with schizophrenia: A longitudinal analysis from the EuroSc study

BACKGROUND

Subjective well-being in people with schizophrenia is likely to be impaired by positive and negative psychotic symptoms. However, these may impact differentially on hedonic (satisfaction and interest in life) and eudaemonic (optimal psychological and social functioning) components.

AIMS

We hypothesized that positive symptoms would influence the hedonic component, while negative symptoms would be linked to eudaemonic well-being.

METHODS

We tested this using longitudinal data (N = 1208) from the EUROSC study. Measures were repeated after 6, 12, 18 and 24 months. Hedonic and eudaemonic features were identified using the Quality of Life Interview. Positive and negative symptoms were assessed with the Positive and Negative Syndrome Scale. We used latent variable structural equation modelling to investigate the impact of positive and negative symptoms at each of the four data points on well-being components 6 months later, controlling for depressed mood.

RESULTS

The measurement model yielded acceptable fit. People with higher scores on positive symptoms at a given time-point were more likely to report lower scores for hedonic components six months later (6-, 12-, and 24-month), whereas we found no significant paths from negative symptoms to hedonic or eudaemonic features.

CONCLUSIONS

Although we found a longitudinal influence of positive symptoms on hedonic well-being, negative symptoms had no effect on either hedonic or eudaemonic components. While symptom reduction strategies may be helpful for hedonic well-being, the amelioration of eudaemonic features may require targeted psychosocial programmes to help individuals attain more rewarding lives.

Functioning and Happiness in People with Schizophrenia: Analyzing the Role of Cognitive Impairment

Schizophrenia is associated with marked functional impairment and low levels of subjective happiness. The aim of the current study was to evaluate the relationship between subjective happiness and functioning in patients with schizophrenia, while considering the role of cognitive functioning. Methods: In total, 69 schizophrenia patients and 87 matched healthy controls participated in the study. Patients’ clinical status was assessed, and a series of self-report questionnaires were administered to both patients and healthy controls to measure subjective happiness, satisfaction with life, well-being, functioning, and cognitive impairment. A multiple linear regression model identified significant predictors of subjective happiness and related constructs. Results: Schizophrenia participants endorsed lower levels of happiness and well-being, and higher perceived stress compared to healthy controls. In schizophrenia patients, there was an inverse and significant correlation (r = −0.435; p = 0.013) between subjective happiness and functioning in a subgroup of patients without cognitive impairment. This correlation was not significant (r = −0.175; p = 0.300) in the subgroup with cognitive impairment. When controlling for other clinical variables (by multiple lineal regression), the severity of symptoms and level of insight failed to demonstrate significant relationships with happiness; meanwhile, perceived stress and some specific cognitive dominions (as verbal learning and processing speed) were associated with satisfaction of life of the patients. Conclusions: The relationship between subjective happiness and functioning in schizophrenia patients was influenced by level of cognitive impairment. Findings from this study suggest that rehabilitation programs may improve recovery outcomes with a focus on subjective happiness and functioning, especially in patients with cognitive impairment. Future research is needed to better understand the complex interplay between subjective happiness, functioning, and cognitive impairment in patients with schizophrenia.
