Recollections of Parental Rejection,Self-Criticism and Depression in Suicidality

The present study examines whether self-criticism and depressive symptoms mediate the relationship between recollections of parental rejection and suicidality. A community sample of 200 Portuguese adults completed, in counterbalanced order, a socio-demographic questionnaire, the short form of the Inventory for Assessing Memories of Parental Rearing Behaviour (EMBU), the Depressive Experiences Questionnaire (DEQ), the Center for Epidemiologic Studies Depression Scale (CES-D), and reports of any suicide intention and/or ideation and suicide attempts. Structural Equation Modeling (SEM) indicated that recollections of parental rejection are significantly associated with depressive symptoms and suicidality. Recollections of parental rejection are indirectly associated with depressive symptoms and suicidality through self-criticism. The association between self-criticism and suicidality is mediated by depressive symptoms. In addition to a significant direct association between recollections of parental rejection and suicidality, the final model indicated that recollections of parental rejection are significantly associated with self-criticism. That same self-criticism is significantly associated with depressive symptoms which, in turn, are significantly associated with suicidality. Individuals with recollections of parental rejection are at greater risk for suicide ideation and behavior, possibly because such experiences predispose them to intense self-criticism which is a risk factor for depression associated with suicidal ideation and behavior.     

Fall risk and gait in Parkinson's disease: The role of the LRRK2 G2019S mutation

Patients with Parkinson's disease (PD) who carry the G2019S mutation (a glycine to serine substitution at amino acid 2019) in the leucine‐rich repeat kinase 2 (LRRK2) gene are generally believed to be clinically indistinguishable from patients with sporadic PD. There are, however, conflicting reports on the relationship between the mutation and the motor phenotype. We quantitatively compared gait and mobility in patients with PD carriers of the G2019S mutation to non‐carrier patients with PD to better understand the genotype‐phenotype relationship. Fifty patients with PD carriers of the G2019S LRRK2 mutation and 50 age, disease duration, and disease severity matched PD non‐carriers were studied. An accelerometer quantified gait under three walking conditions: usual‐walking, dual‐tasking, and fast‐walking. The Unified Parkinson's Disease Rating Scale classified patients into PD sub‐types and the Timed Up and Go quantified mobility and fall risk. In all three walking conditions, gait variability was larger and the walking pattern was less consistent among the PD mutation carriers (P < 0.016). The PD carriers also took longer to complete the Timed Up and Go (P = 0.011) and were more likely to report having fallen in the previous year (P = 0.018). 64% of the PD carriers were classified as belonging to the postural‐instability‐gait‐difficulty (PIGD) sub‐type compared to only 17% of the PD non‐carriers (P < 0.0001). Among patients with PD, the G2019S mutation in the LRRK2 gene is apparently associated with increased gait variability, an increased fall risk, and the PIGD sub‐type. Therapeutic approach specifically designed to delay gait disturbances and falls may be justified in patients who carry the G2019S mutation. © 2013 International Parkinson and Movement Disorder Society     

Personality,Cognition, and Adaptability to the COVID-19 Pandemic: Associations with Loneliness,Distress, and Positive and Negative Mood States

The current research examined personality and individual difference factors associated with the perceived ability to adapt to the significant challenges accompanying the ongoing public health crisis concerning the COVID-19 pandemic. This cross-sectional study investigated the associations among self-reported adaptability to the pandemic and personality predispositions (dependency, self-criticism, mattering, and self-esteem), cognitive factors (positive, negative, and loneliness automatic thoughts), loneliness, distress, and mood states. A sample of 462 college students from Israel completed an online questionnaire after 10 weeks of social distancing during the COVID-19 pandemic. The results confirmed that personality vulnerability factors underscored by a negative sense of self (i.e., self-criticism and dependency) and individual difference factors reflecting self-esteem, feelings of mattering, and fear of not mattering are associated in meaningful ways with adaptability to the pandemic, loneliness, distress, negative mood states, and positive mood states. Most notably, higher self-reported adaptability to the pandemic is associated with lower dependency, self-criticism, and fear of not mattering, and higher levels of self-esteem and mattering. The findings attest to the central role of adaptability and related individual difference factors in acclimatizing to the numerous changes and challenges associated with the COVID-19 crisis. The theoretical and practical implications of our findings are discussed.
