[The validation of a questionnaire for measuring the organizational climate in health centers]

To check the reliability and to analyse the validity of a questionnaire on organisational atmosphere (OA).

Crossover and observational.

Primary care teams (PCTs).

Two questionnaires were offered to all the doctors, nurses and social workers (548 professionals) from the 29 PCTs in an autonomous community. One questionnaire was on the OA and the other was a subjective assessment of satisfaction with the structure and functioning of their own team.

When the results were analysed (initial factorial analysis), 3 items with only slight discrimination were eliminated from the OA questionnaire. Construction validity (factorial analysis with varimax method), reliability of the questionnaire (Cronbach's alpha and Spearman-Brown coefficient) and of criterion (correlation between OA and variables in the subjective assessment questionnaire) were calculated. The overall response rate was 77.5% (402 professionals). Three dimensions which explained 57% of total variability and which confirmed adequate construction validity were identified: team-work, cohesion and commitment. "Team-work" comprised 9 items and explained 27.18% of total variability. "Cohesion" had 7 items, which explained 16.55% of variability. Lastly, "Commitment" explained 13.47% of variability, with 5 items. The validity of criterion was adequate (close correlation between OA and subjective assessment of structure and operation). Reliability was high (0.89 alpha and 0.92 Spearman-Brown for the entire questionnaire and > 0.7 for the dimensions).

The reliability and validity of the adapted questionnaire are sufficient and permit its routine primary care use in our health system to be recommended.
