Background: Providing care for schizophrenia patients is complex, and it requires dealing with various psychosocial burdens.Aim: To develop and validate a tool that measures the quality of life and self-stigma (SS) of the schizophrenia patient’s caregiver (QLSSoSPC).Setting: Outpatient psychiatric services clinics in Saudi Arabia.Methods: The current study used a methodological cross-sectional design. A sample of 205 schizophrenia patients’ caregivers was recruited by using a convenient sampling method. Classical Test Theory and Rasch Analysis approaches were used.Results: The developed tool has proven acceptable level of reliability and validity. The analysis confirmed seven-factor structure accounted for 74.4% of the total variance. Cronbach’s reliability statistics for the developed tool were satisfactory and ranged from 0.80 to 0.91.Conclusion: The psychometric properties of the QLSSoSPC tool supported its prospective use and allowing us to recommend the implementation of the tool on behalf of clinical and research purposes.

Abstract Background: Quality of life (QOL) for patients with Peptic ulcer disease (PUD) is of interest worldwide and disease-specific instruments are needed for clinical research and practice. This paper focus on the development and validation of the PUD scale under the system of Quality of Life Instruments for Chronic Diseases (QLICD-PU) by the modular approach and both classical test theory and Generalizability Theory. Methods: The QLICD-PU is developed based on programmatic decision-making procedures, including multiple nominal and focus group discussions, in-depth interviews, and quantitative statistical procedures. Based on the data of 153 PUD inpatients, correlation analysis, factor analysis, t-test, and Generalizability Theory analysis (including generalizability study and decision study, ie. G-study and D-study) were used to assess the validity, reliability, and responsiveness of the scale. Results: When the popular scale health survey short form (SF-36) was used as the standard, correlation and factor analysis confirmed good construct validity and criterion-related validity of QLICD-PU. Except for the social domain (0.62), the internal consistency α of all domains is higher than 0.70. The overall score and the test-retest reliability coefficients (Pearson r and intra-class correlation ICC) in all domains are higher than 0.80 (0.77 in the social domain). After treatments, the overall score and scores of all domains have statistically significant changes (P <0.01), except for social impact and sexual function scores. The SRM (Standardized response mean) of domain-level scores ranges from 0.34 to 1.03. The G coefficient and reliability index (Ф coefficient) further confirm the reliability of the scale through more accurate variance components and decision-making information about changes in the number of items. Conclusions: The QLICD-PU can be used as a useful measurement to assess the quality of life of PUD patients with good psychometric characteristics and multiple advantages.

Based on the data of 153 PUD inpatients, G and D studies using correlation analysis, factor analysis, t-test, and generalized theoretical analysis were used to assess the validity, reliability, and responsiveness of the scale.Results: When SF-36 was used as the standard, correlation and factor analysis confirmed good structural validity and standard-related validity of QLICD-PU. Except for the social domain (0.62), the internal consistency α of all domains is higher than 0.70. The overall score and the retest reliability coefficients (Pearson r and intra-class correlation ICC) in all domains are higher than 0.80 (0.77 in the social domain). After treatment, the overall scores and scores of all domains have statistically significant changes (P <0.01), except for social impact and sexual function scores. The SRM of field-level scores ranges from 0.34 to 1.03. The G coefficient and reliability index (Ф coefficient) further confirm the reliability of the scale through more accurate variance components and decision-making information about changes in the number of items.Conclusions: QLICD-PU can be used as a useful measurement to assess the quality of life of PUD patients with good psychometric characteristics and multiple advantages.
