Early intervention in the family system: A framework and review

A framework for understanding the effect of early intervention on family structure and functioning is presented. The framework uses five sets of variables to characterize families: Their ecology; and the values, roles, personalities, and interactions of family members. Twenty research studies that met criteria of having comparison/control groups, beginning intervention either prenatally or during the first 3 months of infancy, and directing intervention to family functioning are abstracted and examined in detail. Successful and unsuccessful studies are compared as to population and nature of intervention. Two criteria of success are used: (1) The commonly used criterion of any positive change; (2) a more rigorous criterion of change in at least three areas of family functioning, based on the assumption that more pervasive change will have more lasting influence on child development. Application of the first criterion found that 75% of early family focused intervention studies showed a successful outcome. Application of the latter criterion found that 50% showed a successful outcome. Further, there were no significant differences between successful and unsuccessful studies as to target group or type of intervention. The review suggests that early intervention targeted at family functioning is effective and that a more pervasive and sustained effect is likely if the intervention includes at least 11 or more contacts over at least a 3-month period.     

A general rotation criterion and its use in orthogonal rotation

Measures of test parsimony and factor parsimony are defined. Minimizing their weighted sum produces a general rotation criterion for either oblique or orthogonal rotation. The quartimax, varimax and equamax criteria are special cases of the expression. Two new criteria are developed. One of these, the parsimax criterion, apparently gives excellent results. It is argued that one of the most important factors bearing on the choice of a rotation criterion for a particular problem is the amount of information available on the number of factors that should be rotated. This research was supported by the National Research Council of Canada research grant 291-13 to Dr. G. A. Ferguson.     

Bilingual advantage,bidialectal advantage or neither? Comparing performance across three tests of executive function in middle childhood

When bilinguals speak, both fluent language systems become activated in parallel and exert an influence on speech production. As a consequence of maintaining separation between the two linguistic systems, bilinguals are purported to develop enhanced executive control functioning. Like bilinguals, individuals who speak two dialects must also maintain separation between two linguistic systems, albeit to a lesser degree. Across three tests of executive function, we compared bilingual and bidialectal children's performance to that of a monolingual control group. No evidence for a bidialectal advantage was found. However, in line with a growing number of recent partial and failed replications, we observed a significant bilingual advantage only in one measure in one task. This calls the robustness of the bilingual advantage into question. A comprehensive review of studies investigating advantages of inhibitory control and cognitive flexibility in bilingual children reveals that the bilingual advantage is likely to be both task and sample specific, and the interaction between these factors makes qualification of the effect challenging. These findings highlight the importance of tracking the impact of dual linguistic systems across the lifespan using tasks calibrated for difficulty across different ages.     

Positive Psychology Interventions for Chronic Physical Illnesses: A Systematic Review

Positive health focuses on enhancing health along with curing illness to bring about well-being. Treatment for physical illness generally involves drug therapy, while the psycho-social aspects, specifically the positive psychology perspectives, are largely ignored; nevertheless, a growing number of investigations are now studying the effects of positive psychology interventions on health outcomes. The objective of this paper is to systematically review positive psychology interventions in chronic physical illness. A literature search through the databases of EBSCO, PubMed and PsycINFO, reference lists of significant papers and grey literature was conducted following four criteria set for this review. The number of studies selected finally that acceded to the criteria was 14. These studies were analysed by focusing on the study characteristics, kinds of intervention and outcomes of positive psychology interventions. Overall findings reveal that different intervention programmes have been devised by combining various exercises, writing is the most commonly used method for administration and positive psychology interventions are considered feasible and acceptable by patients, but findings about their usefulness are inconclusive. Suggestions for future research, clinical practice and application in communities have been provided which may be useful for clinicians, practitioners and caregivers.     

Challenges associated with a polythetic diagnostic system: criteria combinations in the personality disorders

Converging research on the diagnostic criteria for personality disorders (PDs) reveals that most criteria have different psychometric properties. This finding is inconsistent with the PD diagnostic system according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994), which weights each criterion equally. The purpose of the current study was to examine the potential effects of using equal weights for differentially functioning criteria. Data from over 2,100 outpatients were used to analyze and score response patterns to the diagnostic criteria for 9 PDs within an item response theory framework. Results indicated that combinations that included the same number of endorsed criteria yielded differing estimates of PD traits, depending on which criteria were met. Moreover, trait estimates from subthreshold criteria combinations often overlapped with diagnostic (at-threshold or higher) combinations, indicating that there were subthreshold combinations of criteria that indicated as much or more PD than did some combinations at the diagnostic threshold. These results suggest that counting the number of criteria an individual meets provides only a coarse estimation of his or her PD trait level. Implications for the assessment of polythetically defined mental disorders and for the PD proposal for the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders are discussed.     

THE CONCEPT OF DYNAMIC CRITERIA: A CRITICAL REANALYSIS

Discussions of "the criterion problem" stress the assumedly frequent incidence of dynamic criteria. However, different concepts of dynamic criteria have not been distinguished. Three views of dynamic criteria are clarified in this paper. These are dynamic criteria conceptualized as (a) changes in group average performance over time, (b) changes in validity over time, and (c) changes in the rank-ordering of scores on the criterion over time. The evidence cited for each concept of dynamic criteria is critically analyzed and submitted to significance tests. The results of analyses of 735 r 's and 532 paired r 's across time from studies pertinent to dynamic criteria are reported. It is concluded that dynamic criteria are rare phenomena, with the significant changes found in key studies explainable by methodological artifacts. Though many sources suggest that dynamic criteria have dire consequences for the overall selection process, we argue that the phenomena have been over-emphasized in the literature, and that practitioners' concern should focus instead on removing sources of criterion unreliability.     

Construct validation of scales derived from the Rorschach method: a review of issues and introduction to the Rorschach rating scale

I suggest the main goal of Rorschach validation should be a refined understanding of what each score means. Toward this end, I review general issues in construct validity, hurdles unique to the Rorschach, and general limitations with validation criteria. I then recommend two approaches for improving criteria so they can begin approximating the gold standards that are necessary for a refined understanding of what scores actually measure. The first is a method for improving expert clinical judgment, and the second is a method for aggregating data across diverse judges. Finally, the Rorschach Rating Scale (RRS) is presented as a criterion tool to be used with either of these approaches to validation. The RRS is a fairly comprehensive summary of the constructs thought to be measured by various Rorschach scoring systems. The utility of the RRS for research and training are discussed, as are other practical, theoretical, and psychometric issues in its application.

Implicit learning: Below the subjective threshold

In this review, we consider three possible criteria by which knowledge might be regarded as implicit or inaccessible: It might be implicit only in the sense that it is difficult to articulate freely, or it might be implicit according to either an objective threshold or a subjective threshold. We evaluate evidence for these criteria in relation to artificial grammar learning, the control of complex systems, and sequence learning, respectively. We argue that the convincing evidence is not yet in, but construing the implicit nature of implicit learning in terms of a subjective threshold is most likely to prove fruitful for future research. Furthermore, the subjective threshold criterion may demarcate qualitatively different types of knowledge. We argue that (1) implicit, rather than explicit, knowledge is often relatively inflexible in transfer to different domains, (2) implicit, rather than explicit, learning occurs when attention is focused on specific items and not underlying rules, and (3) implicit learning and the resulting knowledge are often relatively robust.     

The role of decision processes in remembering and knowing

Participants in recognition memory studies are now often asked to partition recognized items into ones that are accompanied by some recollective experience (those they remember) and ones that are not so accompanied (but which they know were previously encountered). Rather than detecting separate memory systems, such attempts to distinguish between remembering and knowing are better understood as a division of positive recognition responses into those that lie above a second decision criterion (remember) and those that do not (know). As such, the amount of memory associated with knowing is strongly dependent on the placement of the decision criteria. A meta-analysis of published data and a simple experiment tested predictions from the decision process analysis of remember/know responses.     

Muscle Dysmorphia Research Neglects DSM-5 Diagnostic Criteria

This systematic review aimed to collect, evaluate, and synthesize the research on muscle dysmorphia (MD) post official recognition as a specifier for body dysmorphic disorder (BDD) in the DSM-5, and provide recommendations for future research. Literature searches were conducted in four databases to see if inclusion criteria were met. Results revealed 33 studies meeting inclusion criteria, none of which utilized DSM-5 criteria for MD or acknowledged the criterion in their research. Few studies acknowledged the association between MD and BDD, and the methodological quality of recent MD research was considered low due to a lack of clinical samples, measurements not using validated cutoff scores, and the research designs. In conclusion, future MD research is encouraged to utilize DSM-5 diagnostic criteria to better inform clinical practice and significantly improve the methodological quality. As such, more effective treatment options may be developed, reducing the risk of health-harming consequences in these individuals.     

Gender stereotyping and decision processes: extending and reversing the gender bias in fame judgments

M. R. Banaji and A. G. Greenwald (1995) demonstrated a gender bias in fame judgments--that is, an increase in judged fame due to prior processing that was larger for male than for female names. They suggested that participants shift criteria between judging men and women, using the more liberal criterion for judging men. This "criterion-shift" account appeared problematic for a number of reasons. In this article, 3 experiments are reported that were designed to evaluate the criterion-shift account of the gender bias in the false-fame effect against a distribution-shift account. The results were consistent with the criterion-shift account, and they helped to define more precisely the situations in which people may be ready to shift their response criterion on an item-by-item basis. In addition, the results were incompatible with an interpretation of the criterion shift as an artifact of the experimental situation in the experiments reported by M. R. Banaji and A. G. Greenwald.     

Posttraumatic Growth and Optimism in Health-Related Trauma: A Systematic Review

Posttraumatic growth (PTG) research is an emerging area of empirical study, especially within the field of clinical health psychology. Much of the research in this area has thus far focused on determining the correlates and predictors of PTG. This systematic review aimed to evaluate the association between posttraumatic growth and dispositional optimism, specifically in relation to health traumas. Empirical studies that met the inclusion criteria were reviewed according to specific evaluation criteria. Results regarding the relationship between dispositional optimism and posttraumatic growth were found to be equivocal. A number of conceptual and methodological issues were identified and discussed in relation to the field of PTG research. Future directions for research are provided.     

Is there evidence for the use of art therapy in treatment of psychosomatic disorders,eating disorders and crisis? A comparative study of two different systems for evaluation

A comparative study of two different systems for evaluation. Scandinavian Journal of Psychology 53, 47-53. As with any type of treatment the requirement for evidence based practice (EBP) has also affected art therapy (AT) when used as an intervention. This review evaluates the available evidence for using AT for psychosomatic disorders, eating disorders and crisis. The search in Cochrane, Best Practice, AMED, CINAHL, PION, PsycINFO and PubMed from 1987 until now resulted in a huge number of articles but only 32 articles met our criteria for evaluations. The articles were assessed with two evaluation systems, the GRADE system used by the Swedish Council on Health Technology Assessment (SBU) and the US Preventive Services Task Force (USPSTF/Task Force). When comparing the results we found that the GRADE evaluation system rejected the quality in 84% of the 32 studies and the USPSTF/Task Force 41% of these studies. An evidence base for AT was found only according to the criteria of USPSTF/Task Force. Hence, the evidence concept is not explicit, which means that effective treatments run a risk of not being implemented in health care. We suggest a broader view of what constitutes evidence in order to make it possible to include different types of research designs and methods.     

The Case for Rules in Reasoning

A number of theoretical positions in psychology—including variants of case-based reasoning, instance-based analogy, and connectionist models—maintain that abstract rules are not involved in human reasoning, or at best play a minor role. Other views hold that the use of abstract rules is a core aspect of human reasoning. We propose eight criteria for determining whether or not people use abstract rules in reasoning, and examine evidence relevant to each criterion for several rule systems. We argue that there is substantial evidence that several different inferential rules, including modus ponens, contractual rules, causal rules, and the law of large numbers, are used in solving everyday problems. We discuss the implications for various theoretical positions and consider hybrid mechanisms that combine aspects of instance and rule models.     

Risk and dynamics of violence in Asperger's syndrome: A systematic review of the literature

The main purpose of this article is to delineate findings from a review of the literature on the empirical basis for the existence of a relationship between Asperger's syndrome (AS) and violence risk. A second aim is to examine whether certain characteristics of the disorder may have a higher violence-triggering potential. Results of this review show that there are very few empirical studies that confirm a stable link between AS and violence. Only 11 studies involving 22 patients and 29 violent incidents met the criteria for inclusion in the review after the search of the literature. However, a qualitative analysis of the studies yielded some indications of possible patterns of dynamics of violence that may prove to be typical of persons with AS. A tentative comparison of AS and psychopathy indicated that there may be qualitative differences in the characteristics of violent behavior between the disorders. Suggestions for further research are presented.     

Clinical and research diagnostic criteria for developmental coordination disorder: a review and discussion

The aim of this review was to investigate the selection criteria used in the past in studies of children with developmental motor problems (excluding those suffering from neurological dysfunctions such as cerebral palsy, muscular dystrophy, etc.). We therefore conducted an extensive analysis of 176 publications. First, an overview of the main characteristics of these studies (terminology, population, type and purpose) and the selection criteria that are reported in these publications are presented. Following this, the DSM-IV selection criteria for developmental coordination disorder (DCD) are contrasted with the selection criteria reported in 41 publications that have used this terminology to classify the children. The results of this comparison show that the inclusion criteria are largely followed, albeit with little consistency concerning selection instruments and quantitative cut-offs, while adherence to the exclusion criteria is not common practice. Strengths and weaknesses of the DSM-IV criteria, complementary to the previous discussion by Henderson and Barnett in the HMS special issue on DCD in 1998 on this same topic, are discussed. The results of the review also show that many studies have used additional selection criteria related to the specific research questions of the study concerned. In the broader context of clinical practice as well as basic research, the latter result suggests the usefulness of a distinction between Clinical Diagnostic Criteria and Research Diagnostic Criteria. This distinction helps to develop a unifying view on the use of diagnostic criteria for research and clinical practice. We conclude with a number of recommendations concerning the selection criteria for children with DCD.     

Dissociating congruence effects in letters versus shapes: Kanji and kana

In order to consolidate the dissociation in feature integration found in earlier studies between letters of the Roman alphabet and corresponding pseudo-letters, the present study used kanji and kana and corresponding pseudo-letters, presented visually, either in isolation or surrounded by congruent or incongruent shape, as targets in a choice-response task with three different response criteria. When the criterion was shape, congruence effects were obtained for both real and pseudo-letters. With the second and third response criteria this result was found for pseudo-letters, but not for letters. These criteria either involved distinguishing between letters and visually similar pseudo-letters or distinguishing between visually similar letters. The dissociation of congruence effects between letters and pseudo-letters was therefore shown to depend on visual similarity between targets, independent of their category. This effect was found to be robust for kanji but not for kana, which is related to distinctions between these two writing systems.     

On the measurement of criterion noise in signal detection theory: the case of recognition memory

Traditional approaches within the framework of signal detection theory (SDT; Green & Swets, 1966), especially in the field of recognition memory, assume that the positioning of response criteria is not a noisy process. Recent work (Benjamin, Diaz, & Wee, 2009; Mueller & Weidemann, 2008) has challenged this assumption, arguing not only for the existence of criterion noise but also for its large magnitude and substantive contribution to individuals' performance. A review of these recent approaches for the measurement of criterion noise in SDT identifies several shortcomings and confoundings. A reanalysis of Benjamin et al.'s (2009) data sets as well as the results from a new experimental method indicate that the different forms of criterion noise proposed in the recognition memory literature are of very low magnitudes, and they do not provide a significant improvement over the account already given by traditional SDT without criterion noise.     

The Utility of Homogeneous Subgroups and Individual Information in Prediction

A number of behavioral research studies have employed subgroups of subjects for prediction. In using subgroups for predictive purposes, a key assumption is often overlooked, i.e., at least one of the grouping or predictor dimensions affects the relationships between the other grouping dimensions and the criteria. The purposes of the present study were (a) to emphasize this commonly overlooked assumption and (b) to examine empirically the utility of subgroup versus individual information in prediction. Data collected on 509 freshmen in 32 life history subgroups (19 male and 13 female subgroups) were used to evaluate the utility of subgroup information in prediction. Of 24 criteria (college experience data, e.g., academic achievement) predicted by subgroup information, predictive efficiency of four criterion measures was enhanced when subgroup information was added to individual information. However, for the vast majority of the criterion measures, predictive efficiency would have been lost had only subgroup information been used in prediction. It is recommended that researchers carefully evaluate the effects on predictive efficiency when using subgroups rather than individual information in prediction.
