Since its development in 1993, the Trier Social Stress Test (TSST) has been used widely as a psychosocial stress paradigm to activate the sympathetic nervous system and hypothalamic-pituitary-adrenal axis (HPAA) stress systems, stimulating physiological functions (e.g. heart rate) and cortisol secretion. Several methodological variations introduced over the years have led the scientific community to question replication between studies. In this systematic review, we used the Preferred Reporting Items of Systematic Reviews and Meta-Analysis (PRISMA) to synthesize procedure-related data available about the TSST protocol to highlight commonalities and differences across studies. We noted significant discrepancies across studies in how researchers applied the TSST protocol. In particular, we highlight variations in testing procedures (e.g., number of judges, initial number in the arithmetic task, time of the collected saliva samples for cortisol) and discuss possible misinterpretation in comparing findings from studies failing to control for variables or using a modified version from the original protocol. Further, we recommend that researchers use a standardized background questionnaire when using the TSST to identify factors that may influence physiological measurements in tandem with a summary of this review as a protocol guide. More systematic implementation and detailed reporting of TSST methodology will promote study replication, optimize comparison of findings, and foster an informed understanding of factors affecting responses to social stressors in healthy people and those with pathological conditions.

Paced copulation induces conditioned place preference in female rats. The authors examined whether associating almond-scented males with paced copulation induces conditioned partner preference. The paired group received 4 paced copulations with almond-scented males and 4 nonpaced copulations with unscented males sequentially at 4-day intervals. The unpaired group received the opposite order of association, whereas the randomly paired group received random associations. A 4th group received a single pairing. On the final test, females were placed into an open field with 2 males, 1 scented and 1 unscented. Females in the paired group solicited the scented male more frequently, and most chose the scented male for their 1st ejaculation. Thus, an odor paired with paced copulation elicits conditioned partner preference in female rats.

The Vancouver Obsessional‐Compulsive Inventory (VOCI) and the Symmetry Ordering and Arranging Questionnaire (SOAQ) are self‐report measures that assess a wide variety of symptoms and features of obsessive‐compulsive disorder (OCD) including checking, contamination, obsessions, hoarding, “just right”, indecisiveness, and symmetry, ordering and arranging obsessions and compulsions. The original English versions of the VOCI and SOAQ have been shown to demonstrate excellent psychometric properties. The present study examined the reliability and validity of French translations of these measures in a non‐clinical sample, and also involved the collection of supplementary psychometric information about the English versions of the scales from a new sample. Volunteer undergraduate students completed questionnaire packages including the VOCI and SOAQ, as well as measures of obsessive‐compulsive, phobic and depressive symptomatology in their native language of either French or English. Results indicate that the French versions of the VOCI and SOAQ demonstrate similar and excellent psychometric properties to the English versions and that these measures are highly valid and reliable assessment tools for use in clinical and research applications in both languages.
