Motivation is a pervasive force that can affect well-being in a variety of life situations, from the more minor through to the ability to overcome addictions and other serious psychological problems. This book presents empirically supported theories (featuring current concerns theory), questionnaires based on these theories (highlighting the Motivational Structure Questionnaire) and varied interventions based on these, with special emphasis on Systematic Motivational Counselling but also including chapters on such approaches as Personality Systems Interaction Theory, expectancy-based approaches, Motivational Interviewing, logotherapy and several others.
