Validity and Reliability of the Spanish Version of the Athlete Psychological Strain Questionnaire

This study aims to provide data on the reliability and validity of an adapted Spanish version of the Athlete Psychological Strain Questionnaire (APSQ) when administered to Spanish athletes.

A cross-sectional study was developed.

Data were collected from 128 athletes (males n = 71; females n = 57). The tools used in this study were the APSQ; Kessler Psychological Distress Scale; and Depression, Anxiety, and Stress Scales. The intraclass correlation coefficient was used to determine relative reliability, whereas standard error measurement and minimal detectable change were used to evaluate absolute reliability. Bland-Altman plots were employed to assess test-retest agreement and potential systematic bias.

Data indicate that the Spanish version of the APSQ demonstrated satisfactory internal consistency (α: .77-.85) and generally fair to good test-retest reliability (intraclass correlation coefficient: .702; 95% CI, .602-.780). Significant associations were found between the APSQ Spanish version and the Depression, Anxiety, and Stress Scales (ρ = .64-.82), with fair to good agreement, whereas fair to moderate levels of agreement were established between the APSQ Spanish version and the Kessler Psychological Distress Scale (ρ = .53-.75).

These results provide preliminary evidence supporting the use of the APSQ Spanish version for mental health screening among Spanish athletes. However, the lack of absolute reliability raises concerns about its utility for assessing the effects of interventions aimed at improving mental well-being.
