Caregiver Preparedness: A Therapeutic Mechanism and Moderating Factor on Outcomes for the Savvy Caregiver Program.

OBJECTIVES: Evidence-based interventions for dementia caregivers, such as the Savvy Caregiver Program (SC), seek to address skills and knowledge deficits, caregiver burden, depressive symptoms, and grief. Little research has examined mechanisms by which these interventions accomplish their goals. Caregiver preparedness may be a possible mechanism by which caregiver interventions may confer benefits. METHODS: The sample included 76 dementia caregivers who completed the 6-session SC. Participants completed the Anticipatory Grief Scale, Center for Epidemiological Studies-Depression Scale, the Preparedness for Caregiving Scale, and the Zarit Burden Interview-Short Form. RESULTS: A repeated measures ANOVA was utilized to determine the interaction between baseline scores and pre-post change in caregiver preparedness. Analysis significantly predicted caregiver burden, (F(1) = 6.68, p=.012, partial η2=.10), depressive symptom endorsement, (F(1) = 6.41, p=.014, partial η2=.09, and anticipatory grief, (F(1) = 6.22, p=.02, partial η2=.1), post-treatment. CONCLUSIONS: Pre-post change in caregiver preparedness significantly predicted pre-post change across measures of caregiver burden, depressive symptom endorsement, and anticipatory grief. Findings suggest that caregiver preparedness may be one mechanism by which the SC confers positive outcomes. These findings provide an empirical and theoretical basis for tailoring future dementia caregiver interventions. CLINICAL IMPLICATIONS: Clinical Interventions may seek to improve caregiver preparedness and subsequent outcomes through utilization of programs like SC.

Support for incentive-sensitization theory in adolescent ad libitum smokers using ecological momentary assessment.

The incentive-sensitization theory (IST) has emerged as a potentially useful theory in explaining substance addiction. IST postulates that the prolonged use of a substance can alter neural systems that are often involved in incentive motivation and reward processes, leading to an increased "sensitization" to the substance and associated stimuli. However, this increased sensitization is thought to mediate only the individual's craving of the substance (e.g., their "wanting"), not their enjoyment of the substance (e.g., their "liking"), a process that may involve unconscious implicit changes in cognitive networks linked to specific substances. Consequently, IST may better explain the real-world dissonance reported for individuals who want to accomplish long-term substance cessation but fail to do so, a phenomenon that is common in adolescent smokers. Thus, the present study aimed to examine the principles of IST in a sample of 154 adolescent ad libitum smokers (Mage = 16.57, SDage = 1.12, 61.14% male) utilizing ecological momentary assessment. Data were analyzed utilizing a multilevel structural equation model examining changes in positive affect (PA), negative affect (NA), and stress from Time 1 (T1) and Time 2 (T2) as a function of smoking and tested the influence of implicit cognition (specifically, implicit attitudes about smoking [Implicit Association Test (IAT)]) on these associations. Consistent with the principles of IST, results found a modest significant negative association between smoking status at T1 and PA at T2 (B = -0.11, p = .047). This association was further moderated by IAT (B = -0.19, p = .029) and was particularly potentiated at high levels of IAT (B = -0.44, p < .001), compared to low (B = -0.05, p = .663) or mean levels of IAT (B = -0.25, p = .004). Findings from this study provide additional support to the principles underlying IST and indicate that, in adolescents, smoking may result in thwarted PA indicative of a transition from "liking" toward "wanting," and this is especially pronounced among those with stronger implicit smoking cognitions.

Effects of medical cannabis use on physical and psychiatric symptoms across the day among older adults.

INTRODUCTION: Older adults are increasingly using medical cannabis (MC). It is unclear if therapeutic effects increase problematic use patterns. The current study addresses this issue by examining symptom trajectories across the day and using trajectories to predict problematic use. METHODS: One-hundred six older adults (age range 55-74) who endorsed medical conditions approved for treatment using MC were recruited online. Participants received six text messages/day to assess momentary symptoms for 15 days. RESULTS: Participants provided 5,156 momentary assessments across 1,106 use days. Symptom trajectories were examined across the day. There was a decline in all symptoms following use. Negative affect, pain, and nausea evinced momentary negative reinforcement associations with cannabis intoxication. Momentary negative reinforcement was associated with adverse cannabis outcomes. Declines in post-use trauma symptoms and momentary negative reinforcement effects for negative affect were both associated with cannabis use disorder symptoms. DISCUSSION: These data suggest that MC may be effective in reducing common symptom clusters. However, the negative reinforcing effect (i.e., the link between use and symptom relief at the event level) may complicate the therapeutic nature (i.e., symptom reduction). Identifying interventions to maximize benefits while minimizing costs may increase the efficacy and safety of MC in older adults.

Loss-of-Control-Eating Mediates the Relationship between Cannabis-Related Problems and Eating Pathology.

The prevalence of eating pathology among college students has increased significantly in recent years. This coincides with increases in the use of cannabis, both nationally, but also among college students. Problematic cannabis use has been linked to eating pathology in prior research. Research also shows that cannabis may affect appetitive drives linked to food consumption. The current study tested the hypothesis that the association between problem cannabis use and eating pathology was mediated by greater loss of control eating. Cross-sectional data were collected from a sample of 805 college student cannabis users at a large Southeastern university in the U.S. The sample were primarily Caucasian (76%) and female (65.22%) with an average age of 20.15 (SD = 3.91). Participants completed surveys assessing eating outcomes (loss of control eating and eating pathology), cannabis use, and cannabis-related problems. The analysis used an observed variable path model. After controlling for cannabis use, cannabis-related problems were indirectly linked to eating pathology via loss of control eating (B = 0.109, SE = 0.025, p < .001), supporting the primary hypothesis. The direct relationship between cannabis-related problems and eating pathology was fully accounted for (B = 0.010, SE = 0.028, p = .724) by the indirect effect of loss of control eating. These data suggest that the association between problematic forms of cannabis use and eating pathology may be due to the association between cannabis problems and loss of control eating. While this may be due to changes in appetite and food evaluation as a function of more problematic use patterns, it may also be that individuals with problematic cannabis use have more problematic eating patterns due to deficits in adaptive coping strategies. Future research should seek to parse out these different potential explanations.
