Efficacy of a Manualized and Workbook-Driven Individual Treatment for Social Anxiety Disorder

Social anxiety disorder is a prevalent and impairing disorder for which viable cognitive-behavioral therapies exist. However, these treatments have not been easily packaged for dissemination and may be underutilized as a result. The current study reports on the findings of a randomized controlled trial of a manualized and workbook-driven individual cognitive-behavioral treatment for social anxiety disorder (Hope, Heimberg, Juster, & Turk, 2000; Hope, Heimberg, & Turk, 2006). This treatment package was derived from an empirically supported group treatment for social anxiety disorder and intended for broad dissemination, but it has not previously been subjected to empirical examination on its own. As a first step in that examination, 38 clients seeking treatment for social anxiety disorder at either the Adult Anxiety Clinic of Temple University or the Anxiety Disorders Clinic of the University of Nebraska-Lincoln were randomly assigned to receive either immediate treatment with this cognitive-behavioral treatment package or treatment delayed for 20 weeks. Evaluation at the posttreatment/postdelay period revealed substantially greater improvements among immediate treatment clients on interviewer-rated and self-report measures of social anxiety and impairment. Three-month follow-up assessment revealed maintenance of gains. Clinical implications and directions for future research are discussed.     

The adaptation of Chinese adolescents in two societies: a comparison of Chinese adolescents in Hong Kong and Australia

This study aimed to compare the adaptation of two groups of migrant Chinese adolescents with their nonmigrant peers. The migrant adolescents included 55 Chinese migrant adolescents who migrated to Australia (Chinese‐Australian) and 111 China‐born adolescents who migrated to Hong Kong (Chinese‐Hong Kong). The nonmigrant adolescents included 157 Anglo‐Australian adolescents residing in Australia and 456 Hong Kong‐born Chinese adolescents residing in Hong Kong. There were three research questions in this study. First, would there be any differences in the adaptation of Chinese migrant adolescents in different societies of settlement? Second, would migrant adolescents experience more adaptation problems than nonmigrant adolescents? Third, would there be any differences in the adaptation of adolescents in the two societies, Australia and Hong Kong? It was hypothesized that: (1) mainland Chinese migrant adolescents in Hong Kong would experience more adaptation problems than Chinese migrant adolescents in Australia; (2) migrant adolescents would report better adaptation than nonmigrant adolescents; (3) adolescents in Hong Kong would report poorer adaptation than adolescents in Australia. The participants were requested to complete a questionnaire on various adaptation outcome measures including life satisfaction, self‐esteem, psychological symptoms, academic satisfaction, and behaviour problems. The results indicated that Chinese‐Australian adolescents reported better psychological adaptation but Chinese‐Hong Kong adolescents reported better sociocultural adaptation. Adolescents resident in Australia reported higher psychological adaptation but lower sociocultural adaptation than those in Hong Kong. Migrant adolescents reported better psychological and sociocultural adaptation than their nonmigrant counterparts. The results were discussed in relation to the social and educational systems of the two societies.     

VIDEO MODELING TO TRAIN STAFF TO IMPLEMENT DISCRETE‐TRIAL INSTRUCTION

Three new direct‐service staff participated in a program that used a video model to train target skills needed to conduct a discrete‐trial session. Percentage accuracy in completing a discrete‐trial teaching session was evaluated using a multiple baseline design across participants. During baseline, performances ranged from a mean of 12% to 63% accuracy. During video modeling, there was an immediate increase in accuracy to a mean of 98%, 85%, and 94% for each participant. Performance during maintenance and generalization probes remained at high levels. Results suggest that video modeling can be an effective technique to train staff to conduct discrete‐trial sessions.     

BRAND PLACEMENT AND CONSUMER CHOICE: AN IN‐STORE EXPERIMENT

An in‐store experiment was performed to investigate the effects of shelf placement (high, middle, low) on consumers' purchases of potato chips. Placement of potato chips on the middle shelf was associated with the highest percentage of purchases. The results confirm the importance of item placement as a factor in consumers' buying behavior.     

Separation Anxiety,Perceived Controllability,and Homesickness1

The present study examined the multidimensional interactionism model of anxiety, stress, and coping by investigating trait separation anxiety, controllability, and homesickness in 152 university students living away from home. Participants completed measures of trait separation anxiety, state anxiety, perceived controllability of the situation, and homesickness. Correlational tests confirmed that trait separation anxiety and homesickness were associated. Also, low perceived controllability was associated with state anxiety and homesickness. Finally, tests of a mediational model confirmed that both perceived controllability of the situation and state anxiety are significant mediators of the association between trait separation anxiety and homesickness. The findings provide support for models of homesickness that focus on diminished sense of personal control and proximity to attachment figures.     

Experiencing Alien-Nation: Effects of a simulation intervention on attitudes toward homosexuals

The authors explored psychological mechanisms underlying a teaching exercise [Hillman, J., & Martin, R. A. (2002). Lessons about gay and lesbian lives: A spaceship exercise. Teaching of Psychology, 29, 308-311] that may improve attitudes toward homosexuals. Heterosexual participants were randomly assigned to a simulation intervention or control lecture condition. In the simulation condition, participants imagined life on an alien planet that inadvertently simulated situational constraints parallel to those faced by homosexuals. The simulation (vs. control lecture) produced significantly more intergroup perspective-taking, empathy, and favorable attitudes toward homosexuals and marginalized groups. Tests of a structural equation model supported the assumption that the simulation (vs. control) provided an experience that heightened intergroup perspective-taking, which indirectly predicted favorable attitudes via independent cognitive (inclusive intergroup representations) and affective (empathy) paths. The model held after statistically controlling for prior attitudes and ideological individual differences predicting anti-homosexual bias. Implications for prejudice-reduction simulations and intergroup contact are considered.     

Traveling economically through memory space: Characterizing output order in memory for serial order

How do people report the contents of short-term memory when information about order must be retained but items can be retrieved in any order? We report an experiment using an unconstrained reconstruction task in which people can report list items in any order but must place them in their correct serial positions. We found (1) a tendency to report recent items first in immediate but not in delayed reconstruction, (2) a tendency to recall temporally isolated items first, (3) a preference for forward recall order, and (4) a preference for output orders that minimize the length of the path that must be traversed through memory space during retrieval. The results constrain most current models of short-term memory in which retrieval is ballistic and is assumed to run to completion autonomously once initiated.     

Pronominal Resolution and Gap Filling in Agrammatic Aphasia: Evidence from Eye Movements

This paper reports the results of three studies examining comprehension and real-time processing of pronominal (Experiment 1) and Wh-movement (Experiments 2 and 3) structures in agrammatic and unimpaired speakers using eyetracking. We asked the following questions: (a) Is off-line comprehension of these constructions impaired in agrammatic listeners?, (b) Do agrammatic, like unimpaired, listeners show eye movement patterns indicative of automatic pronominal reference resolution and/or gap-filling?, and (c) Do eyetracking patterns differ when sentences are correctly versus incorrectly interpreted, or do automatic processes prevail in spite of comprehension failure? Results showed that off-line comprehension of both pronoun and Wh-movement structures was impaired in our agrammatic cohort. However, the aphasic participants showed visual evidence of real-time reference resolution as they processed binding structures, including both pronouns and reflexives, as did our unimpaired control participants. Similarly, both the patients and the control participants showed patterns consistent with successful gap filling during processing of Wh-movement structures. For neither pronominal nor movement structures did we find evidence of delayed processing. Notably, these patterns were found for the aphasic participants even when they incorrectly interpreted target sentences, with the exception of object relative constructions. For incorrectly interpreted sentences, we found end of sentence lexical competition effects. These findings indicate that aberrant lexical integration, rather than representational deficits or generally slowed processing, may underlie agrammatic aphasic listener’s comprehension failure.     

Intelligence and persisting with medication for two years: Analysis in a randomised controlled trial

The study examined whether verbal intelligence is associated with persisting to take medication for up to two years. The design is a prospective follow-up of compliance with taking medication in high-risk individuals participating in a randomised, placebo-controlled trial set in Central Scotland. Participants were 1993 people aged between 50 and 77 years with an ankle brachial index ≤ 0.95. The medication was 100 mg aspirin or placebo daily.The principal outcome measure was continuing with taking medication or stopping it due to having ‘changed one's mind’. Higher verbal intelligence was associated with a greater likelihood of continuing to take medication up to two years after randomisation. For a standard deviation increase in Mill Hill Vocabulary Scale score, risk of stopping medication in the first two years of the study was 0.75 (95% CI 0.64 to 0.87, p < 0.001). Comparing the highest and lowest quartiles of IQ, the lowest IQ group's relative rate of stopping medication was 2.51 (95% CI 1.52 to 4.22). The effect was not attenuated after adjustment for sex, smoking, or level of deprivation. Verbal intelligence is associated with continuing, medium-to-long term engagement with health self-care, even in the face of uncertainty about whether active treatment is being received, whether the treatment is known to be effective in general, and whether it will be helpful to the individual taking it. Such persisting with potentially helpful health behaviours in the face of uncertainty might partly explain why people with higher intelligence live longer and suffer less morbidity from chronic diseases.     

Does Discussion Group Composition Affect Policy Preferences? Results from Three Randomized Experiments

We report the results of three randomized experiments designed to assess whether participants' political attitudes are affected by the prediscussion opinions of their discussion mates. The experiments took place during three multisite Deliberative Polls in 2004 and 2005. Participants discussed current political issues within 330 groups of approximately 10 people each. Because the composition of the groups was determined randomly within each location, the demographic and ideological complexion of the discussion groups varied randomly. This paper examines the effects of randomly varying group composition on political opinions expressed after daylong discussion. We find only sporadic evidence of group composition effects. These results run counter to—or at least qualify—a substantial body of theory and laboratory evidence on the influence of group discussion.
