Counsellors' experiences of changing their practice: Learning the psychodynamic‐interpersonal model of therapy

Seven counsellors were interviewed about their experiences of learning and applying a new approach to therapy: the psychodynamic‐interpersonal model. These interviews were analysed using grounded theory — a qualitative approach. Under the core category of ‘changing counselling practice: applying the PI model of therapy’, the material was organised into 10 major categories: difficult feelings; new awareness; therapeutic identity; identifying reasons for choosing how to work; experiencing difficulties in adherence; attributing causes of difficulties; ways through the difficulties; understanding how change in practice occurs; changing interventions; and specific other inputs. Examples from the interviews are used to cast light on the difficulties experienced by counsellors in the process of changing their practice.     

Structural differences in parent and child reports of children's symptoms of depression and anxiety

Two cohorts of public elementary school children and their parents (assessed 3 years apart) completed child and parent forms of the Children's Depression Inventory (CDI) and the Revised Children's Manifest Anxiety Scale (RCMAS). Assessments were conducted twice, once during the fall (N = 562) and again during the spring (N = 630) of the 6th grade. Factor analyses revealed 3 factors for each measure. Two of the 3 parent CDI factors manifested some degree of congruence with their counterparts from the child CDI. Similarly, 2 of the 3 RCMAS factors were somewhat congruent across informant types. Differences between parent and child factor structures suggest that parents' and children's reports focus on somewhat different aspects of child psychopathology, and they can make qualitatively different contributions to the multiaxial assessment of children.     

Chlordiazepoxide impairs the performance of a learned discrimination

Chlordiazepoxide (CDP) (5 mg/kg) administered on four of eight sessions significantly impaired the performance of a previously learned, reinforcement-cued discrimination in male Sprague-Dawley rats. On four interspersed vehicle-injection sessions, the performance of subjects demonstrated immediate recovery and was indistinguishable from that of controls (0 mg/kg). An analysis of response components indicated that the impairment in discrimination performance was due to a "disinhibitory" effect of the drug on responding during "no-go" phases of the task. The results are discussed in the context of similarities and differences in the effect of CDP on performance and acquisition.     

BEHAVIORAL MANAGEMENT OF EXERCISE TRAINING IN VASCULAR HEADACHE PATIENTS: AN INVESTIGATION OF EXERCISE ADHERENCE AND HEADACHE ACTIVITY

A behavioral package was used to shape and maintain the adherence of 5 subjects with vascular headache to a program of aerobic exercise training. Repeated measures of exercise behavior were examined through the use of a bidirectional changing criterion design. Repeated measures of headache activity were also collected. Results demonstrated a functional relationship between the behavioral package and exercise adherence, because all 5 subjects showed exercise behavior that matched bidirectional changing exercise criteria. The results also indicated clinically significant collateral reductions in vascular headache activity in 4 subjects. Subjects whose aerobic fitness levels were not masked by vasoactive medication also showed measurable increases in aerobic fitness. The results are discussed in terms of the methodology used to demonstrate a functional relationship between the adherence package and exercise behavior and the possible mechanism(s) by which aerobic exercise activity might affect vascular headache activity.     

The Adolescent Activities Checklist: Reliability,standardization data,and factorial validity

This study was conducted to provide standardization data and information on the reliability and factorial validity of the recently developed Adolescent Activities Checklist (AAC). A total of 563 adolescents in grades 7 through 12 served as subjects. Significant main effects for gender, race, and grade were obtained in a multivariate analysis of variance. On the basis of this information, standardization data were established for these three variables. Further investigation indicated that the internal consistency of the AAC was high. In addition, results of a principal components analysis conducted on the frequencies of the Unpleasant and Pleasant Activities subscales revealed four and three factors, respectively. For unpleasant activities, the major dimensions were found to occur in three situations-namely, social interactions, family situations, and school situations. Stressful events also occurred as one of the four unpleasant activities dimensions. For pleasant activities, three dimensions appeared: heterosocial behavior, reinforcing interpersonal situations, and social reinforcement.     

Validation of the reasons for living inventory in general and delinquent adolescent samples

Two studies are reported that discuss the validation of an adult suicide prediction questionnaire for use with adolescents. The Reasons for Living Inventory (RFL; Linehan, Goodstein, Nielsen, & Chiles, 1983) was slightly modified and administered to two samples of adolescents: one from a general high school population and one from a population of juvenile delinquents receiving psychological treatment in a correctional facility. As with adults, adolescents who reported more reasons for staying alive were less apt to report past or recent suicidal thoughts or behaviors. Evidence of convergent validity emerged via correlations of RFL subscales with depression, hopelessness, and other suicide inventories. Evidence of discriminant validity emerged in that correlations with social desirability were not large. Evidence of construct validity emerged in that the RFL subscales related to suicidal thoughts and behaviors over and above depression and hopelessness. Differences between general and delinquent adolescents' reasons for living are discussed.Special gratitude is due to the Indiana Department of Corrections and the Penn-Harris-Madison Public School System for their cooperation and assistance in data collection for this project.     

Computation of cone contrasts for color vision research

Cone-contrast coordinates have proved useful for representing transient test stimuli used in color vision experiments. These representations automatically take into account the spectral absorption of cones and any Weberian adaptation to steady fields of light. Under these conditions, they also can be interpreted as being an approximation to the incremental cone response. A detailed methodology is presented for making appropriate measurements and calculations of cons contrasts for any light source, especially color monitors.     

Visual search for features and conjunctions in development.

Visual search performance was examined in three groups of children 7 to 12 years of age and in young adults. Colour and orientation feature searches and a conjunction search were conducted. Reaction time (RT) showed expected improvements in processing speed with age. Comparisons of RT's on target-present and target-absent trials were consistent with parallel search on the two feature conditions and with serial search in the conjunction condition. The RT results indicated searches for feature and conjunctions were treated similarly for children and adults. However, the youngest children missed more targets at the largest array sizes, most strikingly in conjunction search. Based on an analysis of speed/accuracy trade-offs, we suggest that low target-distractor discriminability leads to an undersampling of array elements, and is responsible for the high number of misses in the youngest children.
