The purpose of this study is to develop a planned intervention in the health care sector in Bahrain to improve the self-control of healthcare employees by using the Behavioral Change Wheel (BCW) anew method for characterizing and designing behavior change. Hence, the study applies a longitudinal methodology to the healthcare sector in the Kingdom of Bahrain for a sample of 64 participants from November 2019 to January 2020. The procedures of this planned change task occupy three stages, based on Kurt Lewin change field theory: Stage 1 (pre-assessment of employees’self-control using the Brief Self Control Scale (BSCS) questionnaire);Stage 2: planned intervention employing the BCW as a new method of change): and Stage 3 (post assessment by repeating the self-control measurement, and comparing the new results with the previous ones). The findings reveal that the 13Items of the Brief Self-Control Scale (BSCS) provided different results over the three stages of the study. In Stage 1 (pre-assessment) the level of self-control level was low, but had improved in stage 3 (post-assessment). This is original research that adds to the body of knowledge by developing and validating a new model in changing human behavior, i.e. the change behavior stages (CBS) model. Practically, this study is the only one of its kind to apply the Brief Self Control Scale (BSCS) and the BCW in the health sector. The BCW has been alsoconfirmed as a “valid” and “reliable” instrument that can be used by future researchers to improve human behavior in organizations.
