Sudden Gains in Depressed Cancer Patients Treated With Behavioral Activation Therapy

Many patients who receive cognitive-behavioral therapy experience sudden gains that are associated with improved treatment response and decreased risk of relapse. Extending prior research, this study examined sudden gains among depressed cancer patients receiving brief (9-session) behavioral activation therapy. Fifty percent of patients experienced sudden gains of large magnitude (M = 11.8 BDI-II points), with sudden gains associated with improved treatment response and maintenance of gains at 3-month follow-up. Relative to those without sudden gains, at pretreatment assessment, cancer patients with sudden gains were more likely to present with less severe depression, less somatic anxiety, fewer coexistent anxiety disorders, as well as less bodily pain, better overall physical functioning, and fewer problems with daily activities as a result of emotional problems. These findings provide increasing support for behavioral activation with a difficult-to-treat population but raise important questions regarding mechanism of change. Clinical implications for treating depressed cancer patients are discussed.     

Tool-composite reuse in wild chimpanzees (Pan troglodytes): archaeologically invisible steps in the technological evolution of early hominins?

Recent etho-archaeological studies of stone-tool use by wild chimpanzees have contributed valuable data towards elucidating the variables that influenced the emergence and development of the first lithic industries among Plio-Pleistocene hominins. Such data help to identify potential behaviours entailed in the first percussive technologies that are invisible in archaeological records. The long-term research site of Bossou in Guinea features a unique chimpanzee community whose members systematically use portable stones as hammers and anvils to crack open nuts in natural as well as in field experimental settings. Here we present the first analysis of repeated reuse of the same tool-composites in wild chimpanzees. Data collected over 5 years of experimental nut-cracking sessions at an “outdoor laboratory” site were assessed for the existence of systematic patterns in the selection of tool-composites, at group and at individual levels. Chimpanzees combined certain stones as hammer and anvil more often than expected by chance, even when taking into account preferences for individual stones by themselves. This may reflect an ability to recognise the nut-cracker as a single tool (composed of two elements, but functional only as a whole), as well as discrimination of tool quality-effectiveness. Through repeatedly combining the same pairs of stones—whether due to preferences for particular composites or for the two elements independently—tool-users may amplify use-wear traces and increase the likelihood of fracturing the stones, and thus of detaching pieces by battering.     

Pain and Depressive Symptoms: Exploring Cognitive Fusion and Self-Compassion in a Moderated Mediation Model

The association between chronic pain (CP) and depression is complex and influenced by several psychological processes. Cognitive fusion (i.e. being entangled with one´s internal experiences) and self-compassion (i.e. being touched by one´s suffering, with a motivation to alleviate it) have been hypothesized as relevant psychological processes in physical and mental health, but few studies have addressed them in CP, and none in a comprehensive model relating pain intensity and depressive symptoms. This study tests, in a moderated mediation model, the mediator role of cognitive fusion between pain intensity and depressive symptoms, and the moderator effect of self-compassion in this mediation. In a cross-sectional study, 231 female CP patients (Age: M?=?48.51, SD?=?10.89) responded online self-report measures. PROCESS, an SPSS macro for conducting path analysis modeling, was used to test the hypothesized model. The model explained 63% of depressive symptoms, and cognitive fusion mediates the association between pain intensity and depressive symptoms. Also, self-compassion moderates this mediation (regardless of self-compassion being low, moderate or high). Although pain intensity is a predictor of depressive symptoms, fusion with thinking in general mediates this association, this relationship is buffered when patients are able to respond to setbacks and perceived shortcomings with self-kindness and warmth. Clinical and theoretical implications are discussed.     

Integrative review on career interventions with unemployed people: Nature,outcomes, and recommendations

The study of career development among unemployed people is vital for effective institutional responses. This integrative review based on Torraco's protocol fills a literature gap by synthesizing research on interventions for this population. Seven keywords, five databases, and six eligibility criteria were defined. Among 324 articles, 36 were reviewed. Findings highlight diverse counseling modalities, emphasizing group interventions and remote delivery. Tailored approaches, including length, frequency, and social-emotional and career dimensions, are crucial. Practical recommendations emphasize comprehensive, psychological support, goal-oriented counseling, and postintervention assistance. These insights underscore vocational psychology's importance in addressing unemployment, impacting government policies, career services, and psychologists.

Validation studies of the Paranoia Checklist (Portuguese version) in mixed sample of patients and healthy controls

Introduction

Paranoid ideation has been consistently found as a phenomenon presented across the population continuum, and a theme that most people find in their everyday thoughts.

The reward probability index: design and validation of a scale measuring access to environmental reward

Behavioral models of depression implicate decreased response-contingent positive reinforcement (RCPR) as critical toward the development and maintenance of depression (Lewinsohn, 1974). Given the absence of a psychometrically sound self-report measure of RCPR, the Reward Probability Index (RPI) was developed to measure access to environmental reward and to approximate actual RCPR. In Study 1 (n = 269), exploratory factor analysis supported a 20-item two-factor model (Reward Probability, Environmental Suppressors) with strong internal consistency (α = .90). In Study 2 (n = 281), confirmatory factor analysis supported this two-factor structure and convergent validity was established through strong correlations between the RPI and measures of activity, avoidance, reinforcement, and depression (r = .65 to .81). Discriminant validity was supported via smaller correlations between the RPI and measures of social support and somatic anxiety (r = – .29 to – .40). Two-week test–retest reliability was strong (r = .69). In Study 3 (n = 33), controlling for depression symptoms, hierarchical regression supported the incremental validity of the RPI in predicting daily diary reports of environmental reward. The RPI represents a parsimonious, reliable, and valid measure that may facilitate understanding of the etiology of depression and its relationship to overt behaviors.     

Relative versus absolute stimulus control in the temporal bisection task

When subjects learn to associate two sample durations with two comparison keys, do they learn to associate the keys with the short and long samples (relational hypothesis), or with the specific sample durations (absolute hypothesis)? We exposed 16 pigeons to an ABA design in which phases A and B corresponded to tasks using samples of 1 s and 4 s, or 4 s and 16 s. Across phases, we varied the mapping between the samples and the keys. For group Relative, short and long samples were always associated with the same keys (e.g., Phase A: ‘1s→ Left, 4s→ Right''; Phase B: ‘4s→ Left, 16s→ Right''); for group Absolute, the 4-s sample was associated always with the same key (e.g., Phase A: ‘1s→ Left, 4s→ Right''; Phase B: ‘16s→ Left, 4s→ Right’). If temporal control is relational, group Relative should learn the new task faster than group Absolute, but if temporal control is absolute, the opposite should occur. We compared the results with the predictions of the Learning-to-Time (LeT) model, which accounts for temporal discrimination in terms of absolute stimulus control and stimulus generalization. The acquisition curves of the two groups were generally consistent with LeT and therefore more consistent with the absolute than the relative hypothesis.
