The Control Beliefs Inventory (CBI)

The control beliefs inventory is a 26-item multidimensional scale designed to assess four specific health-related control beliefs in adults with and without ongoing health issues (general contriol, symptom, control, chance control, and mastery/health self-efficacy). Unlike many other control belief measures it has been developed using both healthy samples and different chronic illness samples.

Although each of the four scales can be used with illness populations it is recommended that the symptom control subscale be omitted when assessing health relevant control beliefs in adults without a current or ongoing health issue (e.g., general adult populations), and that the instructions be changed accordingly. A notable feature of the CBI in comparison to other measures of health related control is that the control subscales do not correlate with self-blame, which can be conceptualised as an extreme and negative form of self-control.

In validity studies with samples of healthy and chronically ill adults, and undergraduates, each subscale demonstrated low correlations with a short version of the Marlowe-Crowne Social Desirability scale (Strahan & Gerbasi, 1972), with correlations ranging from -.01 to .14 for the Health Control Beliefs subscale, -.01 to .04 for the Symptom Control subscale, and .14 to .16 for the Health Self-efficacy subscale.

The CBI is currently available in English, and French (Canadian). However, psychometric properties for the French version are still being investigated. There are four subscales within the 26-item Control Beliefs Inventory. Scale scores are calculated by taking the mean of each subscale, after reverse keying specific items.
