Classical conditioning as the basis for the effective treatment of tinnitus-related distress.

In this paper the history of the emergence of psychological treatments based on the scientist-practitioner model, such as cognitive-behavior therapy, is described. This historical perspective serves to highlight the potential underlying theoretical bases of such approaches. It is argued that the behavioral position need not be abandoned in order to justify the use of so-called cognitive approaches. Indeed, the behaviorist position, far from having outlived its usefulness, remains an important explanatory concept of human behavior and emotion. This theoretical position may also hold the key to identifying features which are shared in common by tinnitus retraining therapy and cognitive-behavior therapy, and which might be responsible for the efficacy of these approaches. Studies are required in which the basic mechanisms responsible for individual responses to tinnitus are identified in order to develop better approaches to assist people to cope with tinnitus.

The relationship between friendship factors and adolescent girls' body image concern, body dissatisfaction, and restrained eating.

OBJECTIVE: This study examined whether poorer friendship relations predict weight concerns and dietary restraint in adolescent girls. METHOD: Questionnaires were administered to 131 Year 9 and Year 10 girls to assess the relationship between acceptance by friends, perceived social support, friendship intimacy, and perceived impact of thinness on male (PITOF-M) and female (PITOF-F) friendships on the one hand, and body image concern, body dissatisfaction, and restrained eating on the other. RESULTS: Friendship variables contributed significantly to the prediction of body image concern, body dissatisfaction, and restrained eating. The largest unique contribution to prediction was from the PITOF-M. Poor acceptance by friends significantly predicted the PITOF-M and PITOF-F. Whereas heavier girls were more likely to believe being thinner would improve their friendships, they did not experience poorer friendships. DISCUSSION: Results suggest sociocultural risk factors for disordered eating and underline the importance of perceived peer affiliation on girls' body image concern and dieting.

Practitioner review: approaches to assessment and treatment of children with DCD: an evaluative review.

BACKGROUND: Movement clumsiness (or Developmental Coordination Disorder--DCD) has gained increasing recognition as a significant condition of childhood. However, some uncertainty still exists about diagnosis. Accordingly, approaches to assessment and treatment are varied, each drawing on distinct theoretical assumptions about the aetiology of the condition and its developmental course. METHOD: This review evaluates the current status of different approaches to motor assessment and treatment for children with DCD. These approaches are divided according to their broad conceptual origin (or explanatory framework): Normative Functional Skill Approach, General Abilities Approach, Neurodevelopmental Theory, Dynamical Systems Theory, and the Cognitive Neuroscientific Approach. CONCLUSIONS: Each conceptual framework is shown to support assessment and treatment methods with varying degrees of conceptual and psychometric integrity. The normative functional skill approach supports the major screening devices for DCD and cognitive (or top-down) approaches to intervention. The general abilities approach and traditional neurodevelopmental theory are not well supported by recent research. The dynamical systems approach supports promising trends in biomechanical or kinematic analysis of movement, ecological task analysis, and task-specific intervention. Finally, and more recently, the cognitive neuroscientific approach has generated some examples of process-oriented assessment and treatment based on validated (brain-behaviour) models of motor control and learning. A multi-level approach to movement assessment and treatment is recommended for DCD, providing a more complete representation of motor development at different levels of function--behavioural, neurocognitive, and emotional.

A prospective longitudinal study of sexual recidivism among adolescent sex offenders.

This paper reports on a follow-up of a sample of 303 adolescent male sex offenders from New South Wales, Australia. Adult rearrest and reconviction data were obtained for 292 of these individuals. The mean observation period between their adjudication as adolescents and their follow-up as adults was 7.3 years. Seventy-five (25%) received further convictions for sexual offenses prior to their 18th birthday. As adults, 25 (9%) came to the attention of police for further alleged sexual offenses, including 14 (5%) who received convictions for these offenses. Of these, 11 (79%) also received new convictions for nonsexual offenses. Overall, 61.3% of subjects received convictions for nonsexual offenses as adults. Results suggest considerable diversity and persistence in delinquent and criminal behavior, and challenge assumptions about high transition rates from adolescent to adult sexual offending.

Procedural learning in children with developmental coordination disorder.

Despite the fact that developmental coordination disorder (DCD) is characterised by a deficit in the ability to learn or automate motor skills, few studies have examined motor learning over repeated trials. In this study we examined procedural learning in a group of 10 children with DCD (aged 8-12 years) and age-matched controls without DCD. The learning task was modelled on that of Nissen and Bullemer. Children performed a serial reaction time (SRT) task in which they were required to learn a spatial sequence that repeated itself every 10 trials. Children were not aware of the repetition. Spatial targets were four (horizontal) locations presented on a computer monitor. Children responded using four response keys with the same horizontal mapping as the stimulus. They were tested over five blocks of 100 trials each. The first four blocks presented the same repeating sequence, while the fifth block was randomised. Procedural learning was indexed by the slope of the regression of RT on blocks 1-4. Results showed that most children displayed strong procedural learning of the sequence, despite having no explicit knowledge about it. Overall, there was no group difference in the magnitude of learning over blocks of trials - most children performed within the normal range. Procedural learning for simple sequential movements appears to be intact in children with DCD. This suggests that cortico-striatal circuits that are strongly implicated in the sequencing of simple movements appear to be function normally in DCD.

Motor imagery training ameliorates motor clumsiness in children.

Children with impaired motor coordination (or developmental coordination disorder) have difficulty representing internally the visuospatial coordinates of intended movements. We have proposed that this deficit reflects impairment in the generation of forward models of the efference copy of intended movements-the efference-copy-deficit hypothesis. In this study, we challenged this hypothesis by examining the efficacy of an imagery intervention designed specifically to train the forward modeling of purposive actions. A pre-post design was adopted. Fifty-four children referred with motor coordination problems were assigned randomly to one of three groups: imagery training, traditional perceptual-motor training, and wait-list control. The imagery protocol-delivered by an interactive CD-ROM-was shown to be equally effective to perceptual-motor training in facilitating the development of motor skill in the referred children. These results support the efference-copy-deficit hypothesis in explaining the cause of motor clumsiness in most children. Directions for future intervention studies and remediation in the field of developmental clumsiness are discussed.

Comparison of cognitive-behavioral group treatment and an alternative non-psychological treatment for chronic low back pain.

This study was designed to investigate the relative efficacy of cognitive-behavioral group treatment, including relaxation training, in comparison with a control condition in a sample of 20 outpatients with chronic low back pain. Subjects in both conditions also received the same physiotherapy back-education and exercise program. The control condition included a control for the attention of the therapist in the cognitive-behavioral treatment. The combined psychological treatment and physiotherapy condition displayed significantly greater improvement than the attention-control and physiotherapy condition at post-treatment on measures of other-rated functional impairment, use of active coping strategies, self-efficacy beliefs, and medication use. These differences were maintained at 6 month follow-up on use of active coping strategies and, to a lesser degree, on self-efficacy beliefs and other-rated functional impairment.

Spatio-visual memory of children with specific language impairment: evidence for generalized processing problems.

BACKGROUND: Children with Specific language Impairment (SLI) have problems with verbal memory, particularly with tasks that have more processing demands. They also have slower speeds of responding for some tasks. AIMS: To identify the extent to which young children with SLI would differ in performance from age-matched non-impaired children on a set of spatio-visual memory tasks. It was predicted that if memory limitations of children with SLI extend beyond the verbal domain to other domains, their performance would be significantly poorer on the spatio-visual tasks than that of the comparison group. It was also predicted that they would be slower in responding. METHODS & PROCEDURES: Six spatio-visual tasks were used to compare the performance of 21 children with SLI, with a mean age of 54.1 months, and 21 age-matched non-impaired children. The tasks ranged in difficulty from simple recall to a search-based working memory task. All tasks were administered though a laptop computer and responses were non-verbal using a touch screen. OUTCOMES & RESULTS: The children with SLI were not significantly slower than the comparison group. However, they were significantly less accurate than the comparison group in recalling patterns, but not in recalling locations. The accuracy for both groups was lower on spatial recall than on pattern recall. The children with SLI were also significantly less able to learn to associate a particular pattern with a particular location, and to have a shorter spatial span. However, on a spatial search task testing working memory, the groups did not differ significantly. CONCLUSIONS: The results indicate that the memory limitations of children with SLI are not restricted to verbal memory, and this fact has implications for its aetiology. Intervention programmes for young children with SLI need to extend beyond language in order to help them develop strategies for processing information in different situations.

The utility of somatic items in the assessment of depression in patients with chronic pain: a comparison of the Zung Self-Rating Depression Scale and the Depression Anxiety Stress Scales in chronic pain and clinical and community samples.

OBJECTIVE: To investigate the role of somatic items in the assessment of depression in chronic pain. METHODS: The Self-Rating Depression Scale was administered to 398 individuals with chronic pain, 313 psychology clinic patients with similar overall levels of depression, and a general population sample of 491. All three samples were also administered the Depression Anxiety Stress Scales. RESULTS: Confirmatory factor analysis of pooled Self-Rating Depression Scale and Depression Anxiety Stress Scales items revealed that Self-Rating Depression Scale items denoting diurnal variation, decreased appetite, weight loss and constipation failed to contribute to depression in all 3 samples. Items denoting tachycardia and irritability also failed to discriminate between depression and a combined anxiety/stress factor in all 3 samples. The chronic pain sample endorsed somatic items, in particular psychomotor retardation, sleep disturbance, constipation, and fatigue, more strongly than the other samples relative to their endorsement of nonsomatic depression items. CONCLUSIONS: It was concluded that depression measures that give emphasis to somatic symptoms provide poor measures of depression severity in any individuals and in patients with chronic pain may lead to an overestimation of the severity of depression. More recently developed instruments avoid these limitations and are also better able to discriminate depression from related states such as anxiety and tension/stress.
