Factor structure, internal consistency and construct validity of the Sheehan Disability Scale in a Spanish primary care sample

Objective: Several recent studies have documented that substantial functional impairment is associated with many of the mental disorders seen in primary care. However, brief measures of mental health-related functional impairment are not commonly applied in primary care settings. The Sheehan Disability Scale (SDS), a three-item instrument for assessing such impairment, is evaluated in this study. Method: A psychometric analysis of the SDS was conducted with a sample of 1001 primary care patients at Kaiser Permanente in Oakland, California. The SDS and the Symptom Driven Diagnostic System for Primary Care assessments were completed. Results: The internal consistency reliability of the SDS is high, with coefficient alpha of 0.89. The construct validity was substantiated in two ways. A one-factor model fit the data quite well. Furthermore, patients with each of six psychiatric disorders had significantly higher impairment scores than those who did not. Finally, over 80 percent of the patients with mental disorder diagnoses had an elevated SDS score and nearly 50 percent of those with elevated SDS scores had at least one disorder. Conclusions: The psychometric properties of the SDS were evaluated in primary care. The internal consistency reliability was high. The analyses also lend empirical support for the construct validity. The scale is a sensitive tool for identifying primary care patients with mental health-related functional impairment, who would warrant a diagnostically-oriented mental health assessment.

Background Satisfaction with the medical interview has been rarely explored in primary care outside the UK, despite evidence suggesting that a trustful doctor–patient relationship is a key ingredient to facilitate treatment adherence and relief from illness-related distress. Aims The aims of this study are to analyse the construct validity of the Italian version of the Medical Interview Satisfaction Scale (MISS-21) and its correlations with two outcome measures, the Inventory of Depressive Symptomatology – Self-Report and World Health Organization Quality Of Life Brief Version, in patients with mild-to-moderate depression, recruited in primary care practices. Method The factor structure underlying the MISS-21 was investigated with principal component analysis, and the internal consistency of the factors was evaluated with Cronbach's alpha. Network analysis was used to investigate the interrelationships among items. The importance of individual items in the network structure was determined with centrality analyses. Correlations of MISS-21 scores with changes in depression and quality of life were analysed with Spearman's correlation coefficient. Results The MISS-21 proved to have a robust four-dimensional factor structure. Cronbach's alpha for the factors ranged from 0.77 to 0.93, suggesting good to excellent internal consistency. The four factors identified were positively correlated with improvement in depressive symptoms and three quality-of-life domains. Conclusions The MISS-21 has sound psychometric properties, and comprises four factors related to clinical outcomes, which makes it suitable for clinical and research applications. The central items in the network should be considered as possible targets for quality improvement interventions in primary care.

Background: There are presently no validated scales to adequately measure the stigma of suicide in the community. The Stigma of Suicide Scale (SOSS) is a new scale containing 58 descriptors of a “typical” person who completes suicide. Aims: To validate the SOSS as a tool for assessing stigma toward suicide, to examine the scale’s factor structure, and to assess correlates of stigmatizing attitudes. Method: In March 2010, 676 staff and students at the Australian National University completed the scale in an online survey. The construct validity of the SOSS was assessed by comparing its factors with factors extracted from the Suicide Opinion Questionnaire (SOQ). Results: Three factors were identified: stigma, isolation/depression, and glorification/normalization. Each factor had high internal consistency and strong concurrent validity with the Suicide Opinion Questionnaire. More than 25% of respondents agreed that people who suicided were “weak,” “reckless,” or “selfish.” Respondents who were female, who had a psychology degree, or who spoke only English at home were less stigmatizing. A 16-item version of the scale also demonstrated robust psychometric properties. Conclusions: The SOSS is the first attitudes scale designed to directly measure the stigma of suicide in the community. Results suggest that psychoeducation may successfully reduce stigma.

The current study was planned to test the validity and reliability of the Turkish version of the COVID-19 Literacy Scale. The sample of the study was taken from 473 individuals. In this study, language validity, content validity and construct validity were examined to determine the validity of the scale. Its reliability was evaluated by internal consistency, split-half reliability, and test-retest reliability method. It was defined that the scale has a two-factor structure as a result of EFA and its factor loadings are in the appropriate range (0.852–0.324). According to the CFA result, it was determined that the model-data fit was at a good level. The Cronbach values for the whole scale and subscales were .92, .90, and .87, respectively. It was observed that the test-retest value was .95. It was concluded that the Turkish form of the COVID-19 Literacy Scale is a reliable and valid tool.

Our purpose in this study was to develop a scale to measure preference for online social interaction (POSI). The psychometric properties of the POSI Scale were tested with 2 separate samples of Chinese teenagers (age 13–18 years). The responses of the first group (n = 352) were used to explore the factor structure of the scale. The responses of the second group (n = 593) were used to test construct validity and consistency reliability of the POSI Scale. The results indicated that (a) the POSI Scale consists of three dimensions: online social interaction frequency, online social interaction propensity, and perception of superiority of online social interaction compared to face-to-face social interaction; and (b) the POSI Scale has good structural validity and internal consistency and reliability, and is a reliable and valid instrument for measurement of adolescents' preference for online social interaction, especially in the context of Chinese teenagers.

Research Findings

The reliability and factor structure of the adapted multiple choice version of the Miner Sentence Completion Scale (MSCS). In this study the multiple choice MSCS was adapted as a result of several criticisms thereof. The internal consistency and factor structure of the adapted MSCS were determined to ascertain the reliability and construct validity of the questionnaire. Results show that the internal consistency is unsatisfactory and that the factor structure is so complex that interpretation becomes virtually impossible. In light of the results of this study and other research findings of the psychometric properties of the MSCS, it is recommended that a new measuring instrument for managerial motivation be developed that will enable a valid testing of the managerial rolemotivation theory. Opsomming Na aanleiding van verskeie punte van kritiek teen die MSCS is die meervoudige keuse-MSCS in hierdie studie aangepas. Ten einde 'n aanduiding van die betroubaarheid en konstrukgeldigheid van die aangepaste MSCS te verkry, is die interne konsekwentheid en faktorstruktuur daarvan bepaal. Die resultate dui daarop dat die interne konsekwentheid onbevredigend en die faktorstruktuur te kompleks vir interpretasie is. In die lig van die bevindinge van hierdie studie, en ander navorsingsbevindinge oor die psigometriese eienskappe van die MSCS, word aanbeveel dat 'n nuwe meetinstrument van bestuursmotivering ontwikkel word wat 'n geldige toetsing van die bestuursrol-motiveringsteorie moontlik sal maak.

Background: Patient participation in treatment and care is often encouraged and is desirable because of its proven positive impact on treatment, quality of care and patient safety. Aims: To develop an instrument to measure patient participation in health care and to investigate the measurement properties of the Patient Participation Questionnaire (PPQ). Methods: A literature review was conducted to develop a model of patient participation. The PPQ was constructed consisting of 17 items organized into four subscales. Psychometric evaluation of factor structure, convergent construct validity by hypothesis testing and analyses of internal consistency using Cronbach’s alpha were performed on data from a hospitalised mixed group of patients with cardiac disease, pulmonary disease and cancer ( N=378 patients). Results: Confirmatory factor analysis did not show a clear model fit, which is why an exploratory factor analysis was performed, suggesting a different four subscale structure consisting of a total of 16 items. The four subscales were labelled Shared decision power, Adapted and individualized knowledge, Collaboration and Human approach. There were strong ceiling effects on all items. Analysis of convergent construct validity showed a moderate correlation (0.59) between the PPQ and another instrument measuring patient participation. Internal consistency for the total PPQ score was high: 0.89. Conclusion: In a mixed group of patients with cardiac disease, pulmonary disease and cancer, the PPQ showed promising psychometric properties in terms of factor structure, convergent construct validity and internal consistency. The PPQ may be used to shed light on the experience of patient participation and guide quality improvements.

AbstractGambling urges and gambling refusal self-efficacy beliefs play a major role in the development and maintenance of problem gambling. This study aimed to translate the Gambling Urge Scale (GUS) and the Gambling Refusal Self-Efficacy Questionnaire (GRSEQ) from English to Italian (GUS-I, GRSEQ-I) and to test their factor structure, internal consistency, construct validity, concurrent validity, and gender differences in 513 individuals from the Italian community. Factor structure and construct validity were tested through Confirmatory Factor Analysis, internal consistency through Cronbach’s alpha, concurrent validity through correlations with gambling-related cognitions (GRCS-I), probable pathological gambling (SOGS-I), and gambling functioning (GFA-R-I). Results confirmed that the 6 items of the GUS-I load highly on one dimension of Gambling Urge, and each of the 26 items of the GRSEQ-I load highly on their relevant sub-dimension, among the following: situations/thoughts, drugs, positive emotions, negative emotions. Both scales are internally consistent and show concurrent validity with gambling-related cognitions, probable pathological gambling, and gambling functioning. Males score higher than females at the GUS-I; females score higher than males at the GRSEQ-I. The findings from the present study suggest that the GUS-I and the GRSEQ-I are internally consistent and valid scales for the assessment of gambling urges and gambling refusal self-efficacy in Italian individuals from the community, with significant repercussions in terms of assessment, prevention, and intervention.
