INTRODUCTION New Zealand veterans may have complex mental and physical complaints related to multiple exposures to war environments. They are entitled to, but often do not, access a range of physical, mental health and social services funded through Veterans' Affairs New Zealand. eCHAT (electronic Case-finding and Help Assessment Tool) is a self-completed electronic holistic screen for substance misuse, problem gambling, anger control, physical inactivity, depression, anxiety, exposure to abuse; and assesses whether help is wanted for identified issues.

INTRODUCTION Screening tools assist primary care clinicians to identify mental health, addiction and family violence problems. Electronic tools have many advantages, but there are none yet available in the perinatal context. AIM To assess the acceptability and feasibility of the Maternity Case-finding Help Assessment Tool (MatCHAT), a tool designed to provide e-screening and clinical decision support for depression, anxiety, cigarette smoking, use of alcohol or illicit substances, and family violence among pre- and post-partum women under the care of midwives.

Background: In New Zealand (NZ), 1 in 4 adolescents is affected by mental health issues (eg, depression and anxiety) and engages in risk behaviors (eg, harmful drinking and substance abuse), with rates among Māori youth being significantly higher. The majority of NZ secondary school students visit their local primary health care providers (PHPs) at least annually, yet most do not seek help for mental health and risk behavior (MHB) concerns. While youth think it acceptable to discuss sensitive issues during a consultation with their PHPs, unless problems are severe, such conversations are not initiated by PHPs.

Objectives: This scoping study is the first step of a multiphase, international project aimed at designing a homecare robot that can provide functional support, track physical and psychological well-being, and deliver therapeutic intervention specifically for individuals with mild cognitive impairment.

Design: Observational requirements gathering study.

Participants And Settings: Semistructured interviews were conducted with 3 participant groups: (1) individuals with memory challenges, mild cognitive impairment (MCI), or mild dementia (patients; n = 9); (2) carers of those with MCI or dementia (carers; n = 8); and (3) those with expertise in MCI or dementia research, clinical care, or management (experts; n = 16).

Objective: In order to harness the placebo effect for clinical benefit, more research is needed to determine who might be responsive to a placebo treatment. Recently, a two-faceted Transactional Model of Placebo Responding (TMPR) was offered, which suggests different personality types might respond to different contextual cues. The current study directly tested this model by manipulating treatment descriptors to match the two purported facets of responsiveness.

Background: With a healthcare system burdened by symptomatic and mental-health related conditions, the placebo effect may represent a useful clinical tool. First, however, there is a need to broaden research attention and investigate placebo effects outside laboratories and beyond experimental pain. This study investigated the effectiveness of a take-home placebo treatment in the short-term alleviation of stress, anxiety and symptoms of depression in a non-patient population.

This study investigated trait predictors of placebo responses in the context of inflammatory skin reactions. This was a randomized, cross-over, experimental study using a deceptive placebo protocol. A healthy sample of volunteers (N = 48) completed online personality measures, then attended two laboratory sessions in which short-term inflammatory skin reactions were induced.

Objective: To investigate placebo effects on heart rate (HR) and heart rate variability (HRV) in recovery from a psychosocial stressor.

Methods: A healthy sample underwent two mental arithmetic stress tests in one experimental session. After undergoing the baseline test, participants were randomized into control or placebo groups.

Purpose: To investigate suggestion-induced placebo effects in inflammatory skin reactions.

Methods: A healthy sample of volunteers (N = 48) attended two laboratory sessions. In each, a local short term inflammatory skin reaction was induced with histamine.

The placebo effect is now recognised as a genuine psychobiological phenomenon; however, the question of how it can be systematically harnessed to improve health outcomes is not yet clear. One issue that remains unresolved is why some respond to placebos and others do not. A number of traits have been linked to responding, but findings are scattered.

Aim: To identify personality traits related to placebo responding outside the context of pain.

Methods: Sixty three healthy volunteers completed the study. Personality traits were measured online one week prior to a laboratory session in which two psychosocial stress tests were administered.

Objective: To investigate whether expressive writing could speed wound reepithelialization in healthy, older adults.

Methods: In this randomized controlled trial, 49 healthy older adults aged 64 to 97 years were assigned to write for 20 minutes a day either about upsetting life events (Expressive Writing) or about daily activities (Time Management) for 3 consecutive days. Two weeks postwriting, 4-mm punch biopsy wounds were created on the inner, upper arm.

Objective: This study investigated the placebo effect on experimentally induced skin reactions via the manipulation of expectation.

Methods: Fifty-eight healthy volunteers were randomised into either expectancy or control groups. All participants received a baseline administration of histamine on one arm (Time 1), then a second administration on the other arm, approximately 30 minutes later (Time 2).
