Culture and the behavioural manifestations of traits: an application of the Act Frequency Approach

The behavioural manifestations of Big Five traits were compared across cultures using the Act Frequency Approach. American (n = 176) and Filipino (n = 195) students completed a Big Five measure and act frequency ratings for behaviours performed during the past month. Acts for specific traits cohered to an equivalent degree across cultures. In both cultures, the structure of act composites resembled the Big Five and the strength of trait‐behaviour relationships was very similar. Many acts were multidimensional and analyses revealed cultural commonalities and differences in the relevance and prevalence of acts for the Big Five traits. The results were more consistent with trait than cultural psychology perspectives, because traits predicted behaviour equally well, on average, in the two cultures.

Cognitive-behaviour therapy for chronic fatigue syndrome: comparison of outcomes within and outside the confines of a randomised controlled trial

Outcomes for cognitive-behaviour therapy (CBT) in randomised controlled trials (RCTs) have rarely been compared to those in routine clinical practice. Taking the case of CBT for chronic fatigue syndrome (CFS), we evaluated the results of a successful RCT against those of the same treatment given in the same setting as part of routine practice. Fatigue and social adjustment scores were compared for patients who received CBT for CFS as part of a RCT (N=30) and patients who received CBT as part of everyday clinical practice (N=384). The results in the RCT were superior to those in routine clinical practice. Between pre-treatment and 6-month follow-up, the RCT showed a larger reduction in fatigue and greater improvement in social adjustment than those in routine treatment. The changes in fatigue scores were similar for both groups during treatment but were greater in the RCT between post-treatment and follow-up. Potential reasons for the superior results of the RCT include patient selection, therapist factors and the use of a manualised treatment protocol. Practitioners need to pay particular attention to relapse prevention and ensuring adequate follow-up in addition to encouraging patients to continue with cognitive-behavioural strategies once treatment has ended.     

Universal‐Diverse Orientation,Cognitive Complexity,and Sociopolitical Advocacy in Counselor Trainees

The authors investigated counselor trainees' levels of cognitive complexity and sociopolitical advocacy as predictors of universal‐diverse orientation (UDO). Participants included 120 master's‐ and doctoral‐level trainees from 4 midwestern counseling psychology programs. Results revealed that, after accounting for multicultural social desirability and training experience, actual time spent engaging in sociopolitical advocacy activities uniquely predicted 1 subscale of UDO. Los autores investigaron los niveles de complejidad cognitiva y defensoría sociopolítica de los consejeros en formación como indicadores de predicción de su orientación universal‐diversa (UDO, por sus siglas en inglés). Entre los participantes había 120 estudiantes de maestríay doctorado de 4 programas de psicología clínica en el Medio Oeste de EE.UU. Los resultados revelaron que, después de tomar en cuenta el atractivo social multicultural y la experiencia en formación, el tiempo real dedicado a la participación en actividades de defensoría sociopolítica solo predijo 1 sub‐escala de UDO.     

Social Policies in Uruguay: A View from the Political Dimension of Community Psychology

This paper approaches social policy (SP) from the political perspective considered by Montero (Critical psychology: An introduction, Sage, London, pp 231–244, 1997; Community, Work and Family 1(1):65–78, 1998; Introducción a la Psicología Comunitaria. Desarrollo, conceptos y procesos, Paidos, Buenos Aires, pp 89–114, pp 255–284, 2004; Hacer para transformar. El método en la Psicología Comunitaria, Paidos, Buenos Aires, pp 229–256, 2004) as a paradigmatic dimension of community psychology. The field of SP, the characteristics of certain SPs and the role of SP in the production and reproduction of the subjectivities of those subject to them in Uruguay are described and an analysis given of the challenge posed by going from a compensatory or palliative to a transformative mode of SP. It is proposed that identification of, and understanding and intervention in, psychosocial processes in the field are the keys to maximising the likelihood of SPs assuming a transformative character. Psychosocial aspects and participatory processes implicit in the relationship between the State and civil society are discussed. Finally, some orientations for community psychological intervention in this field of action are proposed.     

Successive positive contrast in one-way avoidance learning

The main finding of these experiments was a positive contrast effect in one-way avoidance learning. Experiment 1 showed that increasing safety time during one-way avoidance training led to improved performance, surpassing that of a control group that had received the high reward (safe time) from the beginning of training. Experiment 2 showed that a similar positive contrast effect occurred when the time spent in the danger compartment before the onset of the warning signal was shortened. These results suggest that time spent in a safe context acts as a reinforcer of the avoidance response; however, its incentive value depends not only on its duration, but also on the length of the time spent in the danger compartment before the onset of the signal. Overall, results also suggest that the avoidance response is a mixture of flight (motivated by fear) and approach (to a safe place) behaviour. The specific weight of the flight or approach component may be a function of the time and the amount of activation of each emotional state (fear or relief) due to opponent homeostatic compensatory processes that occur in the danger and safe compartments during one-way avoidance learning.     

A PRELIMINARY ANALYSIS OF INTERACTIVE EFFECTS BETWEEN COMMON CLASSROOM CONTINGENCIES AND METHYLPHENIDATE

To assess the drug—behavior interaction effects with an 8-year-old boy with attention deficit hyperactivity disorder, common classroom antecedent (e.g., seating arrangement) and consequent (e.g., peer prompts) stimuli were alternated within a school day while drug conditions (methylphenidate vs. placebo) were alternated across days. The results suggested that peer attention maintained disruptive behavior when methylphenidate was absent but not when it was present.     

Whither the Epidemic? Psychoactive Drug-Use Career Patterns of College Students1

Reported nonmedical use and intentions for future use of eight groups of psychoactive drugs were conceptualized and arrayed to represent a person's usage career. Intentions closely predicted usage eight months later. Changes in careers were analyzed from data obtained in surveys of all students at a univeristy in 1968 and three follow-up surveys of the class of 1972. In 1968, the most common order of extent of use of the drug groups was: beer, hard liquor, tobacco, cannabis, depressants, amphetamines, hallucinogens, and narcotics. Students' starting, usage, and intent patterns for the drugs displayed hierarchical, Guttman-like, scalability in approximately this order. Intentions to progress to new drugs on the scale were strong in all classes in 1968. In the class of 1972, however, despite growing experience with the less common drugs as they went through college, intentions to return to more common drugs grew and intentions to progress to new ones decreased, relative to both themselves as freshmen and to equivalent level classes in 1968. The pattern of these changes suggests that it is hazardous to extrapolate from early usage and intent data in predicting the long-term course of usage.
