Background: Adolescents are prone to sleep problems that have unique developmental aspects and contribute to physical, emotional, and behavioural problems. Aims: This study evaluated an individualized, multicomponent intervention that considered developmental factors, and promoted age-appropriate autonomy in three adolescent females with disrupted sleep. Method: Adolescents recorded sleep data on daily logs. A nonconcurrent multiple baseline design was used to evaluate a cognitive-behavioural intervention including sleep hygiene training, bedtime routine development, cognitive restructuring, relaxation training, stimulus control, sleep restriction, bedtime fading, and problem-solving, along with clinically indicated individualization. Results: Outcomes demonstrated clinically meaningful improvements and decreased variability in sleep parameters following intervention. Each participant's sleep log data indicated improvement in, or maintenance of, adequate total sleep time (TST), decreased sleep onset latency (SOL), improved sleep efficiency (SE), improvement in time of sleep onset, and decreased or continued low frequency of night awakenings (NA). Anecdotally, adolescents and parents reported improvement in daytime functioning, coping, and sense of wellbeing. Conclusions: These cases highlight the potential for cognitive-behavioural interventions to facilitate healthy sleep in adolescents with challenging sleep problems.

Background: Clark and Wells’ cognitive model of social anxiety proposes that socially anxious individuals have negative expectations of performance prior to a social event, focus their attention predominantly on themselves and on their negative self-evaluations during an event, and use this negative self-processing to infer that other people are judging them harshly. Aims: The present study tested these propositions. Method: The study used a community sample of 161 adolescents aged 14–18 years. The participants gave a speech in front of a pre-recorded audience acting neutrally, and participants were aware that the projected audience was pre-recorded. Results: As expected, participants with higher levels of social anxiety had more negative performance expectations, higher self-focused attention, and more negative perceptions of the audience. Negative performance expectations and self-focused attention were found to mediate the relationship between social anxiety and audience perception. Conclusions: The findings support Clark and Wells’ cognitive model of social anxiety, which poses that socially anxious individuals have distorted perceptions of the responses of other people because their perceptions are coloured by their negative thoughts and feelings.

Three single participant studies examined effects of in-home parent-implemented Positive Behaviour Support (PBS) interventions on behaviour of individuals with brain injuries. Parental and independent observations of morning routine behaviour or problem behaviour (viz., noncompliance during meals or morning routines, yelling, kicking, swearing, and so on) were taken during baselines and PBS interventions, which consisted of person-centred functional assessments of behaviour, emphasis on changing behavioural antecedents, parent participation in assessing, treating, and evaluating behaviour change, and in-home parent coaching and support. Results show decreased problem behaviour or improved morning routine behaviour, which corroborate and add to the few studies that applied similar parent-implemented interventions. Future comparative studies between PBS and out-patient interventions are indicated.

Social phobia is a common and disabling condition for both children and adults. In recent years Clark and Wells' (1995) cognitive model of social phobia has given rise to an effective treatment protocol for the condition in adults (e.g. Clark et al., 2003, 2006). The current study investigates the applicability of this model to younger people. One hundred and seventy-one 11–14 year-old participants completed questionnaires measuring social anxiety, depression, and the variables hypothesized to maintain social phobia in Clark and Wells' (1995) cognitive model: negative social cognitions, safety behaviours, self-focused attention, and pre- and post-event processing. High socially anxious children scored significantly higher than low socially anxious children on all of the variables in Clark and Wells' model. Negative social cognitions, self-focused attention, safety behaviours, and pre- and post-event processing were all significant predictors of social anxiety, accounting for 48% of the variance in social anxiety. Furthermore, these variables showed specificity to social anxiety, predicting significantly more variance in social anxiety than in depression. Findings suggest that although Clark and Wells' (1995) model of social phobia was developed from research on adult populations, it may be equally applicable to younger people with social phobia.

This short case series aimed to explore whether and how an intervention with a cognitive component changed parental attributions about child behaviour and parents' reports of their own behaviour. The results suggest change in parental attributions, coded using the Leeds Attributional Coding System (LACS), was associated with Problem score changes on the Eyberg Child Behaviour Inventory (ECBI). Changes in parents' reports of their own behaviour were associated with Intensity score changes on the ECBI. However, the changes were in both positive and negative directions. The results call for more understanding of the mechanisms involved in change in parental attributions.
