Description

The Short Form Task-Specific Occupational Self-Efficacy Questionnaire (TSOE-SF) is a psychometric instrument designed to assess individuals’ perceptions of their ability to successfully perform specific occupational tasks and professional responsibilities. The questionnaire evaluates employees’ confidence regarding important workplace competencies, including decision-making, time management, problem-solving, and effective task performance.

The instrument is based on the original Task-Specific Occupational Self-Efficacy Scale developed by Osipow, Temple, and Rooney (1993) and was adapted into Greek by G. Koumoundourou. The Greek adaptation aims to provide a culturally appropriate measure of occupational self-efficacy while maintaining the theoretical foundations and psychometric characteristics of the original instrument.

The short-form version preserves the core dimensions of occupational self-efficacy while offering practical advantages in organizational and research settings due to its reduced administration time. It is particularly suitable for applications involving employees, professionals, and individuals undergoing career or occupational assessment.

Data Analysis and Use

Data collected through the Short Form Task-Specific Occupational Self-Efficacy Questionnaire can be analyzed to examine individuals’ perceived professional competence and confidence in performing occupational tasks.

Descriptive statistical analysis, including calculation of means, standard deviations, and score distributions, can be used to evaluate overall levels of occupational self-efficacy within a sample. Correlation analyses may be conducted to investigate relationships between self-efficacy perceptions and variables such as professional experience, job performance, occupational adjustment, and workplace characteristics.

Factor analysis can be applied to examine the underlying structure of the questionnaire and confirm whether the assessed items adequately represent the dimensions of task-specific occupational self-efficacy.

Comparative analyses between professional groups, organizational sectors, or demographic categories may provide information regarding differences in perceived occupational competence. The results can support personnel development programs, career counseling interventions, and organizational strategies aimed at improving employee confidence and effectiveness.

Objective

The primary objective of the Short Form Task-Specific Occupational Self-Efficacy Questionnaire is to measure an individual’s confidence in their ability to successfully perform specific professional tasks.

The instrument aims to evaluate employees’ perceived competence in essential occupational skills and to provide information regarding areas of professional strength and potential development needs.

By assessing task-specific self-efficacy, the questionnaire contributes to understanding how individuals perceive their capabilities within the workplace and how these perceptions may influence motivation, performance, adaptation, and professional development.

Structure and Content

The short-form questionnaire consists of selected items derived from the original Task-Specific Occupational Self-Efficacy Scale. The items focus on core aspects of occupational functioning and professional competence.

Participants respond using a five-point Likert scale, ranging from 1 = Not at all capable to 5 = Very capable. The brief format allows completion within approximately 5–10 minutes, making it appropriate for use in organizational environments where efficient assessment procedures are required.

The Greek version adapted by Koumoundourou has been applied in professional populations and maintains the focus of the original instrument on occupational self-efficacy and perceived task competence.

Scoring

Each item response is converted into a numerical value ranging from 1 to 5. All items contribute equally to the overall score, which is calculated by summing the individual item responses.

Higher total scores indicate stronger perceived occupational self-efficacy and greater confidence in performing professional tasks. Interpretation of results is recommended through comparison with group averages, normative information, or relevant reference values.

According to the provided scoring framework, scores above 75% of the maximum possible score indicate high occupational self-efficacy, whereas scores below 50% of the maximum score may suggest areas where additional professional support, training, or development may be beneficial.

Statistical Analysis

Statistical evaluation of the questionnaire may include descriptive statistics, reliability analysis, factor analysis, correlation analysis, and comparative procedures.

Mean scores and standard deviations provide information about the general level and variability of occupational self-efficacy within a sample. Correlation analysis can be used to explore relationships between self-efficacy perceptions and occupational variables, such as experience, performance, and professional development indicators.

Factor analysis contributes to the examination of the questionnaire structure and supports evaluation of whether the items represent the intended dimensions of occupational self-efficacy.

Comparisons of mean scores between different occupational or demographic groups may reveal variations in perceived professional competence and identify factors associated with stronger or weaker occupational self-efficacy.

Validity

The Short Form Task-Specific Occupational Self-Efficacy Questionnaire demonstrates evidence of validity through its theoretical alignment with the construct of occupational self-efficacy and through empirical evaluation of the original and adapted versions.

The instrument presents strong content validity because its items address central dimensions of professional confidence and task performance. Convergent and discriminant validity have been examined through relationships with related self-assessment measures and the ability of the scale to differentiate between individuals with different levels of professional experience.

The Greek adaptation by Koumoundourou (2004) provided evidence supporting the applicability and effectiveness of the instrument for assessing occupational self-efficacy within Greek professional populations.

Reliability

The reliability of the questionnaire is supported by satisfactory psychometric findings. According to the provided information, internal consistency coefficients (Cronbach’s alpha) exceed 0.85 across the subscales, indicating strong consistency among the items.

Test–retest reliability over a four-week interval demonstrates correlations above r = 0.80, suggesting good stability of scores over time.

These findings support the use of the instrument as a reliable measure for assessing occupational self-efficacy in both research and applied professional contexts.
