People with neurocognitive disorders (NCD) condition called dementia are mainly taken care by family members. The number of people suffering from neurocognitive disorders is estimated to increase. Providing care for the person with NCD can be stressful and demanding which is why effective interventions to support caregivers are needed. Occupational therapy practitioners have unique knowledge of the person, environment and occupation and how those factors influence on individuals occupational performance. Occupational therapy ́s interventions to support caregivers with NCD have mainly concentrated on problems in the behaviour of person with NCD. The aim of this scoping review was to identify why some caregivers are managing better as a caregiver before any interventions have been done. What are those aspects of Person (P), Occupation (O) and Environment (E) that facilitate occupational performance (OP) when taking care for a person with NCD. PEO-model by Law et. al (Law et al., 1996) was utilized to formulate research question, in search words and in summarizing the results. The search from Ageline, Cinahl, Psycinfo and PubMed databases was done in January 2018 and went back 10 years. Results found 23 relevant articles for inclusion in the scoping review. Facilitating factors emphasized the supports of relationship seen as an overlap of caregivers and individuals with NCD on occupational performance. Facilitating personal factors of resilience, finding gains in caregiving, self -efficacy and religiosity were found to have an impact on care that the caregiver provides. Facilitative aspects of occupations highlighted importance of daily occupations as a source of well-being for both caregiver and person with NCD. In conclusion, facilitating aspects of relationships, personal factors and engagement in activities and hobbies supported occupational performance of both the caregiver and a person with NCD. Taking these factors into consideration could help target interventions more precisely to meet caregivers needs.

This dissertation investigates the psychological processes relevant to consumers relinquishment of decision control to surrogates (e.g., physician, financial advisor). While the first essay investigates the antecedents of relinquishing decision control to surrogates, the second essay focuses on the consequences of such relinquishment of control. The first essay proposes that a key reason for consumers reluctance to relinquish the control of their decisions to expert surrogates is that such relinquishment contradicts their inherent motivation to experience an internal perceived locus of causality (PLOC) for their decisions. Based on this, I hypothesize that consumers become more likely to relinquish decision control either (1) when their motivation to maintain an internal PLOC is weakened or (2) when contextual factors specific to the decision itself are present that shift the anticipated PLOC for it from internal to external. Evidence from three studies provides strong support for this theoretical framework. I show that consumers willingness to relinquish decision control increases when an external PLOC is induced directly (Study 1), when an external event restricts the set of available alternatives (Study 2), and when an incentive to choose a particular alternative is present (Study 3). Based on the self-regulatory strength model and prior research on self-esteem threats, the second essay predicts and shows that delegating decisions to surrogates depletes consumers limited self-regulatory resources more than making the same decisions independently, thus impairing their subsequent ability to exercise self-control. This is the case even though decision delegation actually requires less decision making effort than independent decision making (Study 1). However, the resource depleting effect of decision delegation vanishes when consumers have an opportunity to affirm their belief in free will (Study 2). Moreover, remembering a past decision that one delegated impairs self control more than remembering a decision that one made independently (Studies 3 and 4). The theoretical and practical implications of these findings are discussed. / Marketing
