To examine the content validity, internal structure, and internal consistency of a Peruvian scale assessing reasons why workers are reluctant to attend consultations with a psychiatrist.
Approach:
Study Design: An instrumental study conducted in Peru involving item development, expert validation, pilot testing, and psychometric evaluation.
Sample: Questionnaire administered to 3001 workers from various Peruvian departments using non-random sampling.
Analysis: Exploratory factor analysis and confirmatory analyses were performed, with internal consistency estimated using Cronbach’s alpha, ordinal alpha, and ordinal omega total.
Key Findings:
Most Aiken’s V coefficients were 0.70 or higher, indicating strong relevance and clarity of items, with only one item showing lower representativeness.
Exploratory factor analysis supported a one-factor structure explaining 80.96% of the variance, with factor loadings ranging from 0.8425 to 0.9365.
High reliability estimates were found in both main and sensitivity analyses, indicating the scale's robustness.
Interpretation:
The CONSULT-PSYCHIATR is a brief 10-item instrument with evidence of content validity, internal structure, and internal consistency for assessing perceived reasons for reluctance to attend psychiatric consultations.
Limitations:
Findings may not generalize to other populations and settings, limiting the applicability of the scale beyond the studied group.
Further studies are needed to assess additional sources of validity evidence to strengthen the scale's overall reliability.
Conclusion:
The scale shows promise for identifying barriers to psychiatric consultation among workers in Peru.
