Abstract
Many disturbances of physical, social, and mental health have conditions involving lack of energy, difficulty in making decisions, and low interest or motivation. Laboratory studies of willpower depletion have produced similar states in a temporary fashion. The present review uses extant literature to develop and test three theories about how temporary states of low willpower could become chronic. The first is ongoing and repeated exposure to depleting circumstances, such as caregiver fatigue, burdensome financial debts, and high-stress jobs. The second focuses on inadequate recoveries, such as poor sleep, insufficient nutrition, or unsatisfying vacations. The third invokes dispositional vulnerabilities that predispose some people to become depleted more frequently than others. A wide-ranging search for evidence concluded that the first two theories have more support than the third, though all further merit research. Additional possible contributions to chronicity are discussed, such as the emergence of vicious circles.
