Assessing obsessive compulsive symptoms and cognitions on the internet: evidence for the comparability of paper and Internet administration

Administration of psychological questionnaires via the Internet has gained popularity in recent years and touts many advantages. However, before questionnaires that were originally developed as paper-and-pencil measures can be confidently administered over the Internet, it is necessary to document the equivalence of the paper and computer-generated versions [American Psychological Association. (1986). Guidelines for computer-based tests and interpretations. Washington, DC: American Psychological Association; Cohen, R.J., Swerdlik, M.E., & Smith, D.K. (1992). Psychological testing and assessment (2nd ed.). Mountain View, CA: Mayfield Publishing; Cronbach, L.J. (1990). Essentials in psychological testing (5th ed.). New York: Harper Collins; Meier, S. (1994). The chronic crisis in psychological measurement and assessment: A historical survey. San Diego: Academic Press; Schulenberg, S.E., & Yutrzenka, B.A. (2001). Equivalence of computerized and conventional versions of the Beck Depression Inventory- II (BDI-II). Current Psychology: Developmental, Learning, Personality, Social, 20, 216-230]. The current study tested this equivalence for the Obsessive Compulsive Inventory [Foa, E.B., Kozak, M.J., Salkovskis, P.M, Coles, M.E., & Amir, N. (1998). The validation of a new obsessive compulsive disorder scale: The obsessive-compulsive inventory. Psychological Assessment, 10(3), 206-214] and the Obsessive Beliefs Questionnaire-44 [Obsessive Compulsive Cognitions Working Group. (2005). Psychometric validation of the obsessive belief questionnaire and interpretation of intrusions inventory-Part 2: Factor analyses and testing of a brief version. Behaviour Research and Therapy, 43, 1527-1543] in an unselected student sample. Study results support the equivalence of these measures of obsessive compulsive disorder (OCD) symptoms and beliefs independent of administration method (paper versus secure project website). These findings create new opportunities for conducting OCD-related research online.     

Influence of vocal cues on learning about objects in joint attention contexts

An experimenter taught infants about a novel toy in two joint attention conditions, one with and one without vocal cues. In test trials, infants viewed the familiar toy and a novel toy. Infants in the Joint Attention plus Voice condition looked significantly longer to the novel toy.     

Fear of Hypoglycemia and Self Reported Posttraumatic Stress in Adults with Type I Diabetes Treated by Intensive Regimens

This study investigated the prevalence of hypoglycemic fear (FH) and hypoglycemia-specific posttraumatic stress (PTS) among individuals with Type I diabetes. Over 25% of participants met diagnostic criteria for current PTSD. High percentages of participants endorsed PTS symptom clusters, suggesting that individuals may be experiencing distress without necessarily meeting diagnostic criteria. Hierarchical multiple regression analyses revealed that perceived threat of death from hypoglycemia and FH were significantly related to PTS. Number of recent hypoglycemic episodes did not predict PTS/PTSD. Depression and nonspecific anxiety did not contribute to the statistical prediction of PTSD, suggesting that symptomatology endorsed represents hypoglycemia-specific anxiety rather than global psychological distress. The hypothesis that greater PTS symptomatology would relate to poorer glycemic control was unsubstantiated. Perceived death-threat from hypoglycemia and nonspecific anxiety were the only variables that contributed to prediction of glycemic control, suggesting that PTS did not represent a significant barrier for glycemic control in this sample.     

Learning is impaired by activated intentions

Two experiments examined the task interference that sometimes accrues from having an intention. In standard prospective memory tasks, latency is often slower to an ongoing task performed concurrently with having an intention than it is when no intention is given. If the locus of this slowing resulted from different attentional allocation policies in the two cases, we predicted that the process of learning a word list would be impaired if participants had an intention rather than if they did not. Four different event-based prospective memory tasks were used in Experiment 1 to demonstrate that worse free recall of a word list resulted when studied with a concurrent intention than with a control condition that had no intention. In that experiment, linking an intention to a distal context that was to occur after learning did not impair free recall. Two time-based tasks were used in Experiment 2 to demonstrate that possessing a time-based prospective memory also hinders learning, unless the intention is linked to a future context that is expected to occur after the study session. In the latter case, no impairment was obtained.     

Motivational interviewing or reminders for glaucoma medication adherence: Results of a multi-site randomised controlled trial

Objective: Nonadherence reduces glaucoma treatment efficacy. Motivational interviewing (MI) is a well-studied adherence intervention, but has not been tested in glaucoma. Reminder interventions also may improve adherence.

Design: 201 patients with glaucoma or ocular hypertension were urn-randomised to receive MI delivered by an ophthalmic technician (OT), usual care or a minimal behavioural intervention (reminder calls).

Main Outcome Measures: Outcomes included electronic monitoring with Medication Event Monitoring System (MEMS) bottles, two self-report adherence measures, patient satisfaction and clinical outcomes. Multilevel modelling was used to test differences in MEMS results by group over time; ANCOVA was used to compare groups on other measures.

Results: Reminder calls increased adherence compared to usual care based on MEMS, p = .005, and self-report, p = .04. MI had a nonsignificant effect but produced higher satisfaction than reminder calls, p = .007. Treatment fidelity was high on most measures, with observable differences in behaviour between groups. All groups had high baseline adherence that limited opportunities for change.

Conclusion: Reminder calls, but not MI, led to better adherence than usual care. Although a large literature supports MI, reminder calls might be a cost-effective intervention for patients with high baseline adherence. Replication is needed with less adherent participants.     

Pediatric Whole Exome Sequencing: an Assessment of Parents’ Perceived and Actual Understanding.

Whole exome sequencing (WES) is an integral tool in the diagnosis of genetic conditions in pediatric patients, but concerns have been expressed about the complexity of the information and the possibility for secondary findings that need to be conveyed to those deciding about WES. Currently, there is no validated tool to assess parental understanding of WES. We developed and implemented a survey to assess perceived and actual understanding of WES in parents who consented to clinical WES for their child between July 2013 and May 2015. Fifty-three eligible surveys were returned (57% response rate). Areas with both low perceived and actual understanding about WES included how genes are analyzed and lack of protection against life insurance discrimination. Parents also had low actual understanding for two questions related to secondary findings – reporting of secondary findings in a parent (if tested) and whether secondary findings can be related to traits such as height and hair color. Further work to develop a validated tool to assess understanding of WES would be beneficial as WES is integrated more frequently into clinical care.     

Variability discrimination in humans and animals: implications for adaptive action

Both humans and animals live in a rich world of events. Some events repeat themselves, whereas others constantly change. The authors propose that discriminating this stability, sameness, and uniformity from change, differentness, and diversity is fundamental to adaptive action. Evidence from many areas of behavioral science indicates that the discrimination of and preference for stimulus variability affects both human and animal action. Recent comparative research with humans and animals illustrates a promising approach to the study of these issues. Discovering and understanding the behavioral and neural processes related to stimulus variability and its consequences for behavior offer distinctive challenges and important new opportunities for psychologists and neuroscientists.     

Young children know that trying is not pretending: a test of the "behaving-as-if" construal of children's early concept of pretense

In 3 studies, young children were tested for their understanding of pretend actions. In Studies 1 and 2, pairs of superficially similar behaviors were presented to 26- and 36-month-old children in an imitation game. In one case the behavior was marked as trying (signs of effort), and in the other case as pretending (signs of playfulness). Three-year-olds, and to some degree 2-year-olds, performed the real action themselves (or tried to really perform it) after the trying model, whereas after the pretense model, they only pretended. Study 3 ruled out a simple mimicking explanation by showing that children not only imitated differentially but responded differentially with appropriate productive pretending to pretense models and with appropriate productive tool use to trying models. The findings of the 3 studies demonstrate that by 2 to 3 years of age, children have a concept of pretense as a specific type of intentional activity.
