A mixed-methods process evaluation of a goal management intervention for patients with polyarthritis

Process evaluations of newly developed interventions are necessary to identify effective and less effective intervention components. First aim of this study was to identify key components of a psychosocial goal management intervention from the perspective of participants, and second aim was to evaluate the intervention’s fidelity. A mixed-methods approach was applied to 24 interviews with participants post-intervention and 16 audio recordings of random training sessions. Participants experienced three key components: (1) the content, in which specific exercises helped to raise awareness and (intention to) change goal management behaviour, (2) person-focused approach, specifically, the nurse as trainer and personal fit of the approach, and (3) social mechanisms, including facilitating group processes and interpersonal processes. Adherence to the protocol by the trainers was high, while differences were found in the degree to which they were able to apply the intended collaborative approach and psychological communication skills. The applied design provided valuable insights into the processes that took place. Both the effects experienced by participants in relationship to the content, approach and social mechanisms as well as the strengths and weaknesses found with regard to fidelity provide insights that can inform the development and implementation of person-focused interventions.     

The Relationship Between Orientations to Happiness and Job Satisfaction One Year Later in a Representative Sample of Employees in Switzerland

There are three different routes to happiness: the pleasant life, the good or engaged life, and the meaningful life. These three orientations are positively related with life satisfaction, but the relation with job satisfaction is still not clear. This study examines the relationship between the three orientations to happiness (OTH) and job satisfaction in a 1-year longitudinal study with a representative sample (N = 752, 387 men) of working adults living in Switzerland. This study is part of a larger survey that includes several self-report measures. Regression analyses showed that engagement was positively related with job satisfaction 1 year later. Moreover, when controlling for sociodemographic variables (i.e., age and gender), work-related variables (i.e., household income, managerial responsibility, and financial responsibility), and the five factors of personality (i.e., neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness) the interaction of the three OTH (i.e., pleasure × engagement × meaning), still predicted job satisfaction significantly. Individuals who endorse the three OTH presented the highest job satisfaction 1 year later. Therefore, although engagement is more important for job satisfaction than pleasure or meaning, the best predictor of job satisfaction is the interaction of the three OTH. Thus, people who are high in the three OTH simultaneously enjoy the highest job satisfaction. Future studies should examine whether this relationship is causal.     

Application of piecewise hierarchical linear growth modeling to the study of continuity in behavioral development of baboons (Papio hamadryas)

In behavioral science, developmental discontinuities are thought to arise when the association between an outcome measure and the underlying process changes over time. Sudden changes in behavior across time are often taken to indicate that a reorganization in the outcome-process relationship may have occurred. The authors proposed in this article the use of piecewise hierarchical linear growth modeling as a statistical methodology to search for discontinuities in behavioral development and illustrated its possibilities by applying 2-piece hierarchical linear models to the study of developmental trajectories of baboon (Papio hamadryas) mothers' behavior during their infants' 1st year of life. The authors provided empirical evidence that piecewise growth modeling can be used to determine whether abrupt changes in development trajectories are tied to changes in the underlying process.     

Retrieval does not induce reconsolidation of inhibitory avoidance memory

It has been suggested that retrieval during a nonreinforced test induces reconsolidation instead of extinction of the mnemonic trace. Reconsolidation would preserve the original memory from the labilization induced by its nonreinforced recall through a hitherto uncharacterized mechanism requiring protein synthesis. Given the importance that such a process would have in terms of maintaining, as part of the animal behavioral repertoire, a learned response that has been devalued by experience, we analyzed its existence for the memory associated with a one-trial, step-down inhibitory avoidance task (IA), a memory whose consolidation and extinction require protein synthesis in the CA1 region of the dorsal hippocampus (CA1) and involve the participation of the basolateral amygdala (BLA) and entorhinal cortex (ENT). Rats were trained in IA, and 24 h later they were submitted either to a pure reactivation session (retrieval without stepping down), which was unable by itself to initiate extinction of the avoidance response, or to a second training session. Fifteen minutes before or 3 h after either the reactivation or the retraining sessions, animals were infused with the protein synthesis inhibitor anisomycin (ANI) into CA1, BLA, or ENT. Contrary to the prediction of the reconsolidation hypothesis, none of these treatments affected subsequent memory retention. Because reconsolidation is regarded to be a direct consequence of retrieval, one would expect that, when given before a retention test or a pure reactivation session, enhancers of memory expression should permanently improve retention and, therefore, facilitate retrieval both in that and in subsequent sessions. Using two well-known retrieval enhancers, noradrenaline and adrenocorticotropin(1-24), we could not find any evidence suggestive of reconsolidation. Hence, our results indicate that there is no retrieval-induced, protein synthesis-dependent process that would cause reconsolidation of IA memory.     

Different time course for the memory facilitating effect of bicuculline in hippocampus, entorhinal cortex, and posterior parietal cortex of rats

Several lines of evidence indicate that gamma-aminobutyric acid (GABA) type A (GABA(A)) receptors regulate memory consolidation. Here we studied the effect on consolidation of the selective antagonist of GABA(A) receptors, bicuculline, given into several regions of the cortex at different times after one-trial step-down inhibitory avoidance (0.5 mA, 2-s footshock). Rats were bilaterally implanted with cannulae aimed at the CA1 region of the dorsal hippocampus, entorhinal cortex or posterior parietal cortex, three areas known to be involved in the memory consolidation of this task. At different times after training, bicuculline (0.5 microg/side) was infused into the above mentioned structures. Bicuculline increased memory retention when administered either immediately or 1.5h after training into CA1, and both immediately and 3h after training in the entorhinal or parietal cortex. Thus, in agreement with previous findings using other drugs, the response was biphasic in these latter structures. This suggests that GABAergic mechanisms normally downregulate, memory processing by inhibiting on-going activities necessary for consolidation at the times in which bicuculline was effective in each structure. Based on previous findings, in the hippocampus, such activity involves a number of receptors and signaling pathways in the first 1.5h after training. In the entorhinal and parietal cortex memory-related activities include the participation of protein kinase A and extracellularly regulated kinase (ERK) twice, right after training and then again 3h later.     

Function transformation without reinforcement

In studies of function transformation, participants initially are taught to match stimuli in the presence of a contextual cue, X; the stimuli to be matched bear some formal relation to each other, for example, a relation of opposition or difference. In a second phase, the participants are taught to match arbitrary stimuli (say, A and B) in the presence of X. In a final test, A often displays behavioral functions that differ from those of B, and can be predicted from the nature of the relation associated with X in the initial training phase. Here we report function-transformation effects in the absence of selection responses and of their reinforcers. In three experiments with college students, exposure to relations of difference or identity modified the responses given to later stimuli. In Experiment 1, responses to a test stimulus A varied depending on preexposure to pairs of colors that were distinct from A but exemplified relations of difference or identity. In Experiment 2, a stimulus A acquired distinct functions, depending on its previous pairing with a contextual cue X that had itself been paired with identity or difference among colors. Experiment 3 confirmed the results of Experiment 2 with a modified design. Our data are consistent with the notion that relations of identity or difference can serve as stimuli for Pavlovian processes, and, in compound with other cues, produce apparent function-transformation effects.     

Preliminary validation of a Spanish version of the Sport Motivation Scale

The Sport Motivation Scale was developed in French and later translated into English and validated by Pelletier, et al. in 1995. It is based on the principles of self-determination theory. In this study the scale was translated into Spanish to assess and validate it for a sample of 275 athletes (78 women and 197 men) whose mean age was 21.3 yr. (SD=3.8) and who represented eight sports (track and field, tennis, swimming, waterpolo, soccer, basketball, handball, and volleyball). The Spanish version showed satisfactory internal consistency (Cronbach alpha of .70 to .80) and temporal stability (test-retest r = .69 to .74) over a 4-wk. period. A confirmatory factor analysis partially supported the seven-factor structure. Correlations among the subscales indicated a simplex pattern supporting the construct validity of the scale. Sex differences were found. Taken together, these findings support use of the Spanish version for assessment of motivation in sport.     

Counteraction between overshadowing and degraded contingency treatments: support for the extended comparator hypothesis

Four experiments using rats in a Pavlovian lick-suppression preparation investigated the effects of combining 2 treatments known for their response-decrementing effects, namely, overshadowing and degraded contingency. Contrary to most contemporary learning theories, the extended comparator hypothesis predicts that these 2 treatments will counteract each other, and therefore, less of a decrement in conditioned responding should be observed than with either treatment alone. Experiments 1 and 2 confirmed this prediction in first-order conditioning and sensory preconditioning preparations, respectively. Experiment 3 demonstrated that posttraining extinction of the training context resulted in a recovery from degraded contingency and reversed the counteractive effect on overshadowing. Finally, Experiment 4 demonstrated that posttraining extinction of the overshadowing stimulus resulted in recovery from simple overshadowing and also reversed the counteractive effect on degraded contingency. These results are consistent with the extended comparator hypothesis but not traditional or recent acquisition-focused models.
