The Sherer Self-efficacy Scale demonstrates high reliability and validity in Spanish populations, including clinical groups. Its scores correlate with self-control and assertiveness, supporting its clinical and research utility.
Area of Science:
- Psychology
- Clinical Psychology
- Psychometrics
Background:
- Self-efficacy is a key psychological construct influencing behavior and well-being.
- Assessing self-efficacy accurately is crucial for both clinical practice and research.
- The Sherer, et al. Self-efficacy Scale is a widely used measure, but its psychometric properties require validation in diverse linguistic and cultural contexts.
Purpose of the Study:
- To analyze the validity and reliability of the Sherer, et al. Self-efficacy Scale in a Spanish sample.
- To examine the scale's factor structure and its correlations with other psychological measures.
- To determine if the scale can differentiate between general population and clinical groups.
Main Methods:
- A sample of 555 Spanish subjects (general population and clinical groups: schizophrenia, eating disorders, drug addiction) was recruited.
- Participants completed the Sherer, et al. Self-efficacy Scale, Eysenck Personality Questionnaire, State-Trait Anxiety Inventory, Assertiveness Inventory, and Self-control Questionnaire.
- Statistical analyses including reliability, factor analysis, and correlational analyses were performed.
Main Results:
- The Self-efficacy Scale demonstrated high reliability for total scores and the general factor, even with low social self-efficacy.
- A bidimensional factor structure was found to be more acceptable than a unidimensional one.
- Self-efficacy scores significantly correlated with self-control and assertiveness.
- Personality and anxiety measures showed expected correlations with specific scale dimensions.
- Significant mean differences were observed between the general population and clinical groups.
Conclusions:
- The Sherer, et al. Self-efficacy Scale is a reliable and valid instrument for assessing self-efficacy in Spanish populations.
- The scale's findings support its utility in clinical practice and research involving Spanish individuals.
- The study highlights the importance of cultural and linguistic adaptation in psychological assessment tools.
