Methamphetamine and paranoia: the methamphetamine experience questionnaire.

ABSTRACT: Paranoia in methamphetamine (MA) users is not well characterized or understood. To investigate this phenomenon, we created the Methamphetamine Experience Questionnaire (MEQ), and tested its reliability and validity in assessing MA-induced paranoia. We administered the MEQ to 274 MA-dependent subjects. Of the total subjects, 45% (123) first experienced paranoia with MA use; 55% did not. Obtaining or using a weapon while paranoid was common (37% and 11% of subjects with MA-induced paranoia, respectively). Test-retest and inter-rater reliability for MA-induced paranoia showed substantial agreement (kappa = .77, p < .05 and kappa = .80, p < .05, respectively). First episodes of paranoia occurred more often with intravenous use of MA, and subsequent episodes at higher doses. There was modest correlation between paranoia on the MEQ and the Brief Symptom Inventory (BSI) paranoid ideation scale (rho = .27, p < .05). As expected, there was a poor correlation between paranoia on the MEQ and the BSI depression scale (rho = .14, p = .07). The MEQ provides useful information on drug use variables that contribute to paranoia commonly associated with MA use. (Am J Addict 2010;00:1-14).

Project description:BackgroundNo studies have examined the association between self-esteem and paranoia developmentally across the critical stages of psychosis emergence. The present study fills this gap and extends previous research by examining how different dimensions, measures, and types of self-esteem relate to daily-life paranoia across at-risk mental states for psychosis (ARMS) and first episode of psychosis (FEP) stages. Furthermore, the moderation effects of momentary anxiety and momentary perceived social support on the association between momentary self-esteem and paranoia were examined.DesignThis study used a multilevel, cross-sectional design.MethodsOne-hundred and thirteen participants (74 ARMS and 39 FEP) were assessed repeatedly over seven consecutive days on levels of momentary paranoia, self-esteem, anxiety and perceived social support using experience sampling methodology. Measures of trait and implicit self-esteem were also collected.ResultsGlobal momentary and trait self-esteem, and their positive and negative dimensions, were related to daily-life paranoia in both ARMS and FEP groups. Conversely, implicit self-esteem was not associated with daily-life paranoia in either group. Anxiety negatively moderated the association between positive self-esteem and lower paranoia, whereas both feeling close to others and feeling cared for by others strengthened this association. However, only feeling cared for by others moderated the association between negative self-esteem and higher paranoia.ConclusionsDifferent types, measures and dimensions of self-esteem are differentially related to paranoia in early psychosis and are influenced by contextual factors in daily-life. This yields a more complex picture of these associations and offers insights that might aid psychological interventions.Practitioner pointsDifferent measures (trait and momentary) and dimensions (positive and negative) of explicit self-esteem are distinctly related to paranoia across risk and first-episode stages of psychosis. Explicit, but not implicit, self-esteem is associated with real-life paranoia in incipient psychosis. Anxiety boosted the association of poor self-esteem and paranoia ideation in daily-life. Social closeness, but feeling cared for by others in particular, interacts with self-esteem tempering the expression of paranoia in real life.

Project description:IntroductionMethamphetamine toxicity is common in the Southwest region of the United States and presents diagnostic and treatment challenges in the pediatric population. The aim of our study was to characterize signs and symptoms of methamphetamine toxicity in pediatric patients, highlighting manifestations unique to this population. Additionally, our study sought to evaluate treatment modalities, specifically antipsychotics, in this population with the intent to characterize their adverse effects.MethodsThis is a retrospective review of pediatric patients (age > 2 months ≤ 18 years) at a tertiary care pediatric hospital with ICD-9 or ICD-10 codes suggestive of stimulant exposure between September 1, 2010, and July 31, 2017. Patients with clinical manifestations of sympathomimetic toxicity and confirmation of methamphetamine on urine drug testing via GC/MS were included. Nature, source, and route of exposure along with clinical manifestations including signs, complications, treatments utilized, and adverse events related to treatment were recorded. Specifically, adverse effects following administration of antipsychotics were studied.ResultsSeventy-nine patients met inclusion criteria: median age 2.0 years. Typical manifestations of sympathomimetic toxicity were common, including tachycardia (93.4%), hypertension (85.7%), agitation (79.7%), and abnormal motor activity (55.8%). The prominence of gastrointestinal signs (26.3%) and unique abnormal motor activity were notable. The most common treatments were intravenous fluids (96.1%) and benzodiazepines (77.9%). Antipsychotics were administered in 40.5% of cases, with haloperidol used in the majority. No patients developed seizures, dystonia, torsades de pointes, or hyperthermia after antipsychotic administration.ConclusionsPediatric patients with methamphetamine toxicity commonly manifest sympathomimetic signs. Antipsychotics were often used as an adjunct treatment in this cohort of patients, and no adverse events were reported. Clinicians should be aware of prominent gastrointestinal signs and abnormal motor activity and neurologic manifestations unique to pediatric patients that will assist in making the correct diagnosis in cases of suspected methamphetamine toxicity.

Project description:BackgroundDue to its potential impact on women's psychological health, assessing perceptions of their childbirth experience is important. The aim of this study was to develop a multidimensional self-reporting questionnaire to evaluate the childbirth experience.MethodsFactors influencing the childbirth experience were identified from a literature review and the results of a previous qualitative study. A total of 25 items were combined from existing instruments or were created de novo. A draft version was pilot tested for face validity with 30 women and submitted for evaluation of its construct validity to 477 primiparous women at one-month post-partum. The recruitment took place in two obstetric clinics from Swiss and French university hospitals. To evaluate the content validity, we compared item responses to general childbirth experience assessments on a numeric, 0 to 10 rating scale. We dichotomized two group assessment scores: "0 to 7" and "8 to 10". We performed an exploratory factor analysis to identify underlying dimensions.ResultsIn total, 291 women completed the questionnaire (response rate = 61%). The responses to 22 items were statistically significant between the 0 to 7 and 8 to 10 groups for the general childbirth experience assessments. An exploratory factor analysis yielded four sub-scales, which were labelled "relationship with staff" (4 items), "emotional status" (3 items), "first moments with the new born," (3 items) and "feelings at one month postpartum" (3 items). All 4 scales had satisfactory internal consistency levels (alpha coefficients from 0.70 to 0.85). The full 25-item version can be used to analyse each item by itself, and the short 4-dimension version can be scored to summarize the general assessment of the childbirth experience.ConclusionsThe Questionnaire for Assessing the Childbirth Experience (QACE) could be useful as a screening instrument to identify women with negative childbirth experiences. It can be used as both a research instrument in its short version and a questionnaire for use in clinical practice in its full version.
