Physiologic reactivity to startling tones in women with posttraumatic stress disorder.

Autonomic and eyeblink reactivity to startling tones were investigated in women with histories of childhood sexual abuse (CSA). Twenty-one women with current posttraumatic stress disorder (PTSD), 23 with lifetime but not current PTSD, and 13 women who never had PTSD listened to 15 95-dB, 500-ms, 1000-Hz tones with a 0-ms rise time while heart rate (HR), skin conductance (SC), and orbicularis oculi electromyogram (EMG) responses were measured. Participants in the current and lifetime PTSD groups produced larger HR responses across tones and showed slower absolute habituation of SC response magnitude compared with the never PTSD group. EMG response magnitudes did not differ among groups. Women with CSA-related PTSD showed increased autonomic reactivity and slower habituation to high-intensity tones similar to that observed in primarily male, combat PTSD samples. This suggests that heightened autonomic responsivity to startling stimuli in PTSD is not gender or event specific.     

Children's Uncertain Responses when Testifying about Alleged Sexual Abuse in Scottish Courts

This study examined the uncertain responses of 56 alleged sexual abuse victims, aged 5–17 years, testifying in Scottish criminal court trials. Don't know/remember ground rules were explained to 38% of the children and each child reported uncertainty in response to 15% of the questions on average. Uncertain responding was associated with expressions of resistance and confusion, questioning context (proportionally more regarding substantive than non‐substantive issues), question content (least to disclosure‐focused questions), utterance type (more to directives, particularly those posed by defense lawyers; more to recall‐based than recognition prompts), and age (children in mid‐adolescence were less likely to respond uncertainly than those who were either older or younger). There were no associations between expressions of uncertainty and ground rule administration, or with whether or not the question focused on central rather than peripheral details about the alleged crimes. Findings highlight concerns surrounding preparatory procedures to help witnesses, especially adolescents, indicate uncertainty when testifying. Copyright © 2017 John Wiley & Sons, Ltd.     

Cognitive Behavioral Mobile Applications: Clinical Studies,Marketplace Overview,and Research Agenda

Objective

To review the current literature for evidence regarding the feasibility and efficacy of smartphone-based cognitive-behavioral intervention mobile applications, compare such to the number of applications on the commercial marketplaces, and explore potential steps forward for research in the field.

The Effects of Secret Instructions and Yes/no Questions on Maltreated and Non‐maltreated Children's Reports of a Minor Transgression

This study examined the effects of secret instructions (distinguishing between good/bad secrets and encouraging disclosure of bad secrets) and yes/no questions (DID: “Did the toy break?” versus DYR: “Do you remember if the toy broke?”) on 262 maltreated and non‐maltreated children's (age range 4–9 years) reports of a minor transgression. Over two‐thirds of children failed to disclose the transgression in response to free recall (invitations and cued invitations). The secret instruction increased disclosures early in free recall, but was not superior to no instruction when combined with cued invitations. Yes/no questions specifically asking about the transgression elicited disclosures from almost half of the children who had not previously disclosed, and false alarms were rare. DYR questions led to ambiguous responding among a substantial percentage of children, particularly younger children. The findings highlight the difficulties of eliciting transgression disclosures without direct questions. Copyright © 2017 John Wiley & Sons, Ltd.
