An empirical test of a comprehensive model of intrapersonal empowerment in the workplace

A comprehensive model of intrapersonal empowerment in the workplace posits that empowerment mediates the relationship between the social structural context and behavioral outcomes. The social structural context is operationalized as perceptions of role ambiguity, sociopolitical support, access to strategic information and resources, and work unit culture, whereas behavioral outcomes are operationalized as innovativeness and effectiveness. The model is examined on a sample of 324 middle managers from different units of a Fortune 50 organization. Survey data are examined using a series of regression analyses to assess the mediating effect of intrapersonal. Results suggest that intrapersonal empowerment mediates the relationship between some elements of workplace social structure and innovativeness, but not effectiveness. Although not a mediating mechanism for effectiveness, intrapersonal empowerment is nonetheless directly related to effectiveness (as assessed by the respondent's subordinates). Implications of the results are discussed as are study limitations and directions for future research.

A systematic review of the effectiveness of psychoanalysis,psychoanalytic and psychodynamic psychotherapy with adults with intellectual and developmental disabilities: progress and challenges

Objectives: This systematic review aimed to critically appraise the literature on the efficacy and effectiveness of psychoanalysis, psychoanalytic and psychodynamic psychotherapy in adults with intellectual and developmental disabilities (IDD). Method: A systematic search of electronic databases was carried out. The methodological quality of the studies was assessed using a quality assessment tool and comparisons were made with a review of the quality of research on the effectiveness of cognitive behavioural therapy (CBT) for people with IDD. Results: The search yielded 13 papers which provided evidence for the effectiveness but not efficacy of psychoanalytic and psychodynamic psychotherapy; but none were found for psychoanalysis. The quality of the research was generally poor compared to the current research on the effectiveness of CBT. Conclusions: Positive outcomes have been indicated for psychoanalytic and psychodynamic psychotherapy with people with IDD. Larger scale, more controlled research is necessary to advance the evidence base.     

Cue effectiveness in communicatively efficient discourse production

Recent years have seen a surge in accounts motivated by information theory that consider language production to be partially driven by a preference for communicative efficiency. Evidence from discourse production (i.e., production beyond the sentence level) has been argued to suggest that speakers distribute information across discourse so as to hold the conditional per-word entropy associated with each word constant, which would facilitate efficient information transfer (Genzel & Charniak, 2002). This hypothesis implies that the conditional (contextualized) probabilities of linguistic units affect speakers' preferences during production. Here, we extend this work in two ways. First, we explore how preceding cues are integrated into contextualized probabilities, a question which so far has received little to no attention. Specifically, we investigate how a cue's maximal informativity about upcoming words (the cue's effectiveness) decays as a function of the cue's recency. Based on properties of linguistic discourses as well as properties of human memory, we analytically derive a model of cue effectiveness decay and evaluate it against cross-linguistic data from 12 languages. Second, we relate the information theoretic accounts of discourse production to well-established mechanistic (activation-based) accounts: We relate contextualized probability distributions over words to their relative activation in a lexical network given preceding discourse.     

Revisiting ‘What works for whom?’: A qualitative framework for evaluating clinical effectiveness in child psychotherapy

This paper describes a framework for evaluating the effectiveness of child psychotherapy used by child psychotherapists in an inner city Child and Adolescent Mental Health Service (CAMHS). The Hopes and Expectations for Treatment Approach (HETA) involves using the assessment for psychotherapy that normally precedes treatment to derive a baseline from which to generate a set of hopes/expectations as regards the effects of the treatment on the part of parents and the psychotherapist, to be revisited one year after the start of the psychotherapy and/or at its completion. The Strength and Difficulties Questionnaire, for parents and schools, was also administered before and after the treatment. The characteristics of the first 30 children referred for psychotherapy over a particular time period are described. Of the first 15 children in this group to complete one year of individual psychotherapy, all showed change or significant change in the areas concerning parents' and therapists' hopes at the end-of-year review, as rated by parents and psychotherapists. A case of a child with conduct disorder is used to describe how the assessment generated a psychoanalytic formulation, how the therapist's understanding was fed back to the parents, and how the parents' and therapist's hopes and expectations were derived and recorded. This case illustrates powerfully the impact of trauma in the parents' backgrounds on the internal world of the child, and how the method provides a useful bridge between parent and child work. Feedback from the psychotherapists, the parents and the referrers using the framework is reviewed, and in conclusion the paper argues for the framework's value in promoting good practice in the treatment and management of complex cases and in enhancing awareness of the nature and scope of the psychotherapy process.     

Anxiety,anticipation and contextual information: A test of attentional control theory

We tested the assumptions of Attentional Control Theory (ACT) by examining the impact of anxiety on anticipation using a dynamic, time-constrained task. Moreover, we examined the involvement of high- and low-level cognitive processes in anticipation and how their importance may interact with anxiety. Skilled and less-skilled tennis players anticipated the shots of opponents under low- and high-anxiety conditions. Participants viewed three types of video stimuli, each depicting different levels of contextual information. Performance effectiveness (response accuracy) and processing efficiency (response accuracy divided by corresponding mental effort) were measured. Skilled players recorded higher levels of response accuracy and processing efficiency compared to less-skilled counterparts. Processing efficiency significantly decreased under high- compared to low-anxiety conditions. No difference in response accuracy was observed. When reviewing directional errors, anxiety was most detrimental to performance in the condition conveying only contextual information, suggesting that anxiety may have a greater impact on high-level (top-down) cognitive processes, potentially due to a shift in attentional control. Our findings provide partial support for ACT; anxiety elicited greater decrements in processing efficiency than performance effectiveness, possibly due to predominance of the stimulus-driven attentional system.     

Transportability of equivalence-based programmed instruction: efficacy and efficiency in a college classroom

College students in a psychology research-methods course learned concepts related to inferential statistics and hypothesis decision making. One group received equivalence-based instruction on conditional discriminations that were expected to promote the emergence of many untaught, academically useful abilities (i.e., stimulus equivalence group). A negative control group received no instruction, and a positive (complete instruction) control group received instruction on all possible relations (those taught to, and emerging untaught in, the stimulus equivalence group). On posttests, the stimulus equivalence group performed as well as the positive control group (and both outperformed the negative control group), but those in the equivalence-based instruction condition achieved this outcome with significantly less training, thereby demonstrating the efficiency of equivalence-based instruction. Social validity measures indicated that participants found the instruction to be beneficial and as enjoyable as traditional teaching methods.     

Performance of Mental Health Counselors in Integrated Primary and Behavioral Health Care

Integrated primary and behavioral health care (IPBH) is becoming a preferred mode of service delivery in the United States. Integrated care includes the participation of medical and mental health professionals, such as mental health counselors. The clinical outcomes of these professionals need to be studied to determine their effectiveness in such settings. We examined the performance of 10 mental health counselors on the clinical outcome of 1,747 clients treated in an IPBH center. Analyses using growth curve modeling and pre‐post test design revealed that mental health counselors were effective overall, but they differed in client dropout rates and efficiency in reducing clients' initial symptoms. We used the analyses to rank order counselors based on their effectiveness. Counselors who were the most effective varied in their efficiency but demonstrated the lowest client dropout rates. Implications for future research and counseling practice were discussed.     

Evaluation of a High School Peer Group Intervention for At-Risk Youth

The purpose of this paper is to examine the effectiveness of Reconnecting Youth, a prevention program for at-risk high school youth. Data are from a large, independently evaluated effectiveness trial in two diverse urban school districts. A total of 1,218 students participated; 50% were male; average age was 15. We tested whether positive efficacy trial effects could be replicated, and whether any negative behavioral effects occur when clustering high-risk youth. Although mixed program effects were observed at immediate post-intervention, only negative effects were found at 6-month follow-up. These effects included less optimal scores on measures of GPA, Anger, School Connectedness, Conventional Peer Bonding, and Peer High-Risk Behaviors. Overall, we found little support for the use of this social-influence—model intervention aimed at increasing school connectedness for high-risk youth. Further, this study provides evidence that clustering high-risk youth in preventive interventions has the potential for iatrogenic effects.
