Psychometric evaluation of the internalized stigma of mental illness scale for patients with mental illnesses: measurement invariance across time.

ABSTRACT:

Background

The current investigation examined the psychometric properties of the Internalized Stigma of Mental Illness (ISMI) scale in a sample of patients with mental illness. In addition to the internal consistency, test-retest reliability, and concurrent validity that previous studies have tested for the ISMI, we extended the evaluation to its construct validity and measurement invariance using confirmatory factor analysis (CFA).

Methods

Three hundred forty-seven participants completed two questionnaires (i.e., the ISMI and the Depression and Somatic Symptoms Scale [DSSS]), and 162 filled out the ISMI again after 50.23±31.18 days.

Results

The results of this study confirmed the frame structure of the ISMI; however, the Stigma Resistance subscale in the ISMI seemed weak. In addition, internal consistency, test-retest reliability, and concurrent validity were all satisfactory for all subscales and the total score of the ISMI, except for Stigma Resistance (??=?0.66; ICC?=?0.52, and r?=?0.02 to 0.06 with DSSS). Therefore, we hypothesize that Stigma Resistance is a new concept rather than a concept in internalized stigma. The acceptable fit indices supported the measurement invariance of the ISMI across time, and suggested that people with mental illness interpret the ISMI items the same at different times.

Conclusion

The clinical implication of our finding is that clinicians, when they design interventions, may want to use the valid and reliable ISMI without the Stigma Resistance subscale to evaluate the internalized stigma of people with mental illness.

Project description:BackgroundStigma is common among patients with chronic illnesses. It affects the delivery of healthcare for not addressing the psychological components and may interfere with the patient's attendance to necessary health care services. Therefore, a valid and reliable instrument to measure anticipated stigma related to chronic illness is vital to inform possible interventions. This study aimed to translate the Chronic Illness Anticipated Stigma Scale (CIASS) into the Amharic language and evaluate its psychometric properties in Ethiopia.MethodsThe CIASS was translated into Amharic language using standard procedures. The Amharic version was completed by 173 patients (response rate 96%) with chronic illness from three referral hospitals in the Amhara region. Internal consistency was examined through Cronbach's alpha. Construct validity was evaluated by confirmatory factor analysis and convergent validity by using a Pearson correlation of P-value less than or equal to 0.05.ResultsThe internal consistency was estimated at Cronbach alpha of 0.92. By using a structural equation model, and modification indices a model fitness testing was run and shows a root mean squared error of approximation 0.049 (90% CI, 0.012-0.075). The structural validity results in 78.8% of confirmatory factor analysis showed from the extraction of the three-dimension (components). Validity tests for convergent by using Pearson correlation positively correlated with common mental distress and negatively correlated with quality of life-BREF, and the construct validity shows a good valid tool to CIASS.ConclusionThe Amharic language version of the chronic illness anticipated stigma scale shows a satisfactory level of reliability and validity on different psychometric measures of assessment. The tool may be useful for future researchers and patients with chronic illness in the Amharic-speaking population. Moreover, it will be used to see the psychological burden related to chronic illness and for comparison among international population groups.

Project description:IntroductionInternalized stigma is an ongoing process of psychological assimilation of the community labels towards mental illness, in which people with mental illness (PWMI) gradually lose their current positive belief and confidence in themselves and their future wishes. It affects the treatment and help-seeking behavior which leads to poor drug adherence, social marginalization, unemployment, socio-economic devastation, and poor quality of life for PWMI. Therefore, the current study aimed to determine the magnitude and correlates of high internalized stigma among People with Mental Illness (PWMI) attending the outpatient department of Amanuel mental specialized hospital, Addis Ababa, Ethiopia.MethodsInstitution based cross-sectional study was conducted from March 03 to March 28, 2019. A consecutive sampling technique was used to select an estimated 406 study participants. Internalized stigma was assessed using a 29 Item Internalized Stigma of Mental Illness (ISMI-29) tool. Data were entered and analyzed using SPSS 22 software. A Binary logistic regression model was fitted to identify correlates of internalized stigma. An adjusted odds ratio (AOR) with a 95% confidence interval was computed to determine the strength of association and the level of significance was declared with a p-value <0.05.ResultOf the total study participants, 388 respondents agreed to participate in the study giving a response rate of 96%. The magnitude of high internalized stigma among the study participants was 61.3% (95% CI: 58.2, 64.4). Poor social support (AOR = 1.973; 95%CI = 1.189, 3.27) and being unemployed (AOR = 2.87, 95% CI = 1.192-6.931) were significant correlates of high internalized stigma among PWMI.ConclusionOverall, around three in five PWMI experienced high internalized stigma. Poor social support and being unemployed were significant correlates of high internalized stigma. Large scale community-based study supplemented by qualitative design is highly recommended to identify additional correlates of internalized stigma and understand perspectives of PWMI.
