Primary use / Purpose: 

The PIQ inquires about the support for quitting provided by a spouse or living partner.


A number of studies have found that persons whose partners reportedly supported their efforts to quit smoking were more likely to quit smoking and maintain abstinence. Less clear, however, is what kinds of partner behaviours are helpful to quitters and what kinds are harmful. This lack of information about mediating behaviours may be responsible, in part, for the ineffectiveness of interventions designed to facilitate spouse/partner support for quitting smoking. Partner Interaction Questionnaire (PIQ-20) that includes separate subscales assessing positive and negative behaviours provided by a spouse or romantic partner, close friend, or family member. 


For each item, subjects responded on a 5-point scale: never (0), almost never (l), sometimes (2),fairly often (3), and very often (4). Separate scores were calculated for positive and negative behaviors by summing responses to the 10-items within each subscale. Internal reliabilities (Cronbach alphas) for the expectancy PIQ were .89 for the positive scale and .82 for the negative scale. Internal reliabilities for the received PIQ were .89 for the positive scale and .85 for the negative scale.
