Purpose of the Questionnaire

The OCQ questionnaire aims to assess the degree of employees’ commitment to their organization, with emphasis on affective attachment and dedication. It is intended for employees and managers and is widely used both in research contexts and for practical purposes, such as improving organizational culture.

Questionnaire Analysis

The original questionnaire was developed by Mowday, Steers, and Porter (1979) and consists of 15 items. The Greek adaptation was carried out by Stafila, Spyrospolloi, and Plali. The items are based on a 7-point Likert scale (1 = “strongly disagree” to 7 = “strongly agree”). The instrument measures affective commitment without distinguishing between subscales.

Scoring of Items

Each item is rated from 1 to 7. Items 3, 7, 9, 11, 12, and 15 are reverse scored (1=7, 2=6, etc.). The final score is the mean of all responses, with higher values (e.g., 5–7) indicating stronger organizational commitment. Example of interpretation:
Score < 3: Low commitment Score 3–5: Moderate commitment Score > 5: High commitment

Statistical Analysis

In the Greek version, the questionnaire was administered to 69 individuals (managers and subordinates) from 8 organizations in Thessaloniki. The following mean scores were observed:
Overall commitment: 4.56
Managers: 4.70
Subordinates: 4.49

Validity

The OCQ demonstrates acceptable discriminant validity, as confirmed by the original study of Mowday et al. (1979). It is capable of distinguishing between high and low organizational commitment.

Reliability

Cronbach’s alpha ranges from 0.82 to 0.93, with an average of 0.90, indicating excellent internal consistency. This makes the questionnaire reliable for both research and practical applications.
