Many theories of behavior at work fail to consider the effects of the physical environment on employees' behavior and attitudes. The purpose of this research was to gather evidence of the construct validity of the Physical Work Environment Satisfaction Questionnaire (PWESQ) and of the validity of the physical work environment satisfaction construct. Evidence of the construct validity of the PWESQ was sought through its administration, along with a number of established measures of work attitudes, to 641 employees in 8 organizations. The data provided evidence of the validity of both the physical work environment satisfaction construct and the PWESQ as a valid measure of that construct. Practical and theoretical implications, as well as implications for future research, are discussed.
