International Sex Survey (ISS)

Description: About the ISS The International Sex Survey (ISS) is a large, cross-cultural study that examines sexuality, including the positive (e.g., sexual satisfaction, sexual desire) and negative aspects of it (e.g., sexual risk-taking, sexual function problems) via an anonymous online survey. We will donate 50 cents (USD) to non-profit, sexuality-related international organizations (e.g., World Association for Sexual Health) for every completed survey, with a maximum of a 1000 USD donation. The ISS will be conducted with more than 40 participating countries. This way, we can compare the results across different cultures, and have a more comprehensive understanding of sexuality all over the world. Thus, your participation in the study will help with the success of our research.

Specifics: Study Population:
We are recruiting participants over 18 years old.

Participant Obligation:
The research is:
- an online survey
- anonymous
- takes 25-30 minutes

The Impact of COVID-19 on Mental Health

Description: The main purpose of this research is to investigate the impact of the COVID-19 pandemic on the mental health of the general population in Canada as well as factors that may affect this potential impact. The study requires participants to fill out a demographic questionnaire as well as scales measuring anxiety, depression, personality characteristics, social conformity, critical thinking/cognitive flexibility, adaptability to change, ethical values, empathy, and self-efficacy. Consistent with the aim of investigating the impact of the pandemic, we will also ask questions directly related to the virus and associated factors, such as social distancing and preventive behaviours (i.e., mask wearing), COVID-19 risk perception, and impact of the pandemic on various aspects of daily life. All questions and the consent form will be delivered in an electronic format via SurveyMonkey.

Specifics: Study Population:
Participants for the study must be 18+ and living in Canada.

Participant Obligation:
Participation in this research will include electronically completing various questionnaires on the survey platform "SurveyMonkey", which will take approximately 30 - 35 minutes in total to complete.

Eating behaviours, physical symptoms, and quality of life.

Description: The research team is trying to determine how three groups of children and youth are different and similar: (1) children and youth who have a diagnosis of Avoidant Restrictive Food Intake Disorder (ARFID), (2) children and youth who have a diagnosis of Somatic Symptom and Related Disorders (SSRD) with gastrointestinal symptoms, and (3) children and youth who do not have either diagnosis. We are currently inviting families who have a child between the ages of 4-18 who does not have a diagnosis of ARFID or SSRD to participate in this study. For parents of youth aged 8 years and older: both you and your child will be asked to provide your permission to participate (called “consent/assent forms”). On these forms, you and your child will decide which of you will fill out the questionnaires. It could be parent only, youth only, or both. For parents of children aged 4-7 years: only the parent is asked to provide their permission to participate and fill out the questionnaires.

Specifics: Study Population:
You are invited to participate in this study if your child is between the ages of 4-18 years, is generally healthy, and does not have a diagnosis of Avoidant Restrictive Food Intake Disorder (ARFID) or Somatic Symptom or Related Disorder (SSRD).

Participant Obligation: (Limited to 250 characters)
Participating in this study involves filling out five questionnaires online, which is expected to take about 30 minutes.

You will be asked to indicate which group you are a part of, please select group C

Attitudes toward Statistics, Software, Research Practices, and Open Science

Description: Poor statistical and research practices slow down scientific advancement and impact society at large. Such research practices lead to lack of replicable effects and potentially misleading conclusions or results. Open science practices have been widely recommended to help combat against these issues, but researchers are not adopting them too quickly. This study consists of two parts: 1) We will examine the psychometric properties of previously developed measures tapping into attitudes toward statistics for students in a general researcher population as well as questions asking about research practices. After validating the measures in part 1, they will be used in part 2 of the study where we seek to examine attitudes toward statistics, attitudes toward open science practices, and the frequency with which researchers engage in certain research practices. We will use online surveys to assess attitudes toward statistical software and practices in researchers, and determine the extent to which these attitudes are related to the adoption of recommended statistical and open science research practices. Results from the study will help scholars writing about open science and research methods identify important next steps in their own research by disentangling the observed behavioural practices and the reasons behind such practices.

Specifics: Study Population:
Participants will include English-speaking psychology researchers (including PhD students) with at least a Master in psychology (or related) conducting research at a N.American institution (e.g., at a university, hospital, private sector, government):

Participant Obligation:

Technology-Facilitated Sexual Violence as a Micro-Trauma: Understanding its Role in the Development of Traumatic Stress

Description: Little research has investigated technology-facilitated sexual violence (TFSV), and little is known about the psychological impact. Preliminary research suggests that victims of TFSV tend to experience higher rates of anxiety, stress, and depressive symptoms, while also experiencing lower rates of self esteem, perceived control, and social support (Snaychuk & O'Neill, 2020; Cripps, 2016). However, existing research does not typically consider the effect of traumatic stress on victimization, and as a result of victimization. Understanding the factors associated with TFSV may help mitigate the negative consequences experienced by victims. Using a battery of standardized tools to assess various aspects of mental health and TFSV-related questions developed by the researcher, this study seeks to answer the following research questions: 1) what is the prevalence rate of TFSV in the sample and what demographic factors are associated with victimization (age, gender, etc.)? 2) what are the psychological effects (anxiety, stress, depression, trauma) of TFSV and the associated risk/protective factors (social support, perceived control, self-esteem, etc.)? 3) does previous trauma exposure have an effect on the emergence of adverse symptoms following TFSV?

Specifics: Study Population: This study is Canada-wide and is open to all Canadian citizens aged 18+
Participant Obligation: This study will require participants to access an online survey consisting of several questions related to technology-facilitated sexual violence and mental health. The survey will take approximately 30 minutes to complete.

E-mental health care for parents and caregivers struggling with anxiety and depression during COVID-19: Improving access and matching services to need

Description: COVID-19 is having a serious impact on mental health worldwide. Parents/caregivers are experiencing higher rates of anxiety and depression due to increased stressors. Virtual mental health care has become necessary during the pandemic. Internet-based CBT (iCBT) has long-standing evidence of effectiveness for treating anxiety and depression. Existing iCBT does not always provide the necessary content to help parents with pandemic-related distress and/or options to access care in a way that is flexible to the needs of parents with children at home. The present study aims to develop innovative ways to provide equitable and effective mental health care for parents struggling with anxiety and depression during COVID-19 by pursuing three objectives. We will investigate parents’ preferences for levels of iCBT service delivery (unguided, minimally guided, or fully guided) and modality of guidance (phone, in-app messaging, or video chat) during a pandemic; enroll parents in a COVID-adapted iCBT program, Tranquility, with their choice of level of service delivery and analyze whether levels of service delivery predict intervention outcome; and identify which COVID-19 parent stressors are most prevalent and most closely associated with intervention outcome, and how this differs by gender, by using machine learning to mine participants’ written responses as part of their CBT program.

Specifics: Study Population: Parents/caregivers of children under the age of 18 located in New Brunswick (NB), Nova Scotia (NS), or Prince Edward Island (PEI). Participants will be experiencing signs of anxiety or depression.

Participant Obligation: Participants in this study will be asked to engage in an online intervention for parents with anxiety and/or depression. They can choose to work through the intervention on their own or with the support of a coach.

Victim-Perpetrator Relationship Characteristics and Perceptions of Personal Sexual Assault and Coercion Experiences

Description: As many as 50% of women report having experienced some form of sexual violence within their lifetimes, with experiences of sexual violence frequently resulting in negative physical and psychological outcomes. The severity of these negative outcomes can be significantly affected by aspects of the victim-perpetrator relationship. However, little research has been done to identify how else victim-perpetrator relationship characteristics may affect the survivor. The primary aim of this study is to investigate survivors’ perceptions of their own sexual assault/coercion experiences in relation to victim-perpetrator relationship characteristics. These relationship characteristics will include a) the length of time the survivor has known the perpetrator, b) how close the survivor feels to the perpetrator, c) whether or not the survivor maintains contact with the perpetrator, and d) the type of victim-perpetrator relationship (coworker, romantic partner, friend etc.). Three relationship characteristics specifically looking at romantic relationships will also be included (whether the relationship is casual or serious, satisfaction, and commitment). The investigated perceptions will fall into three domains: a) emotional reactions to the sexually assaultive/coercive event, b) allocation of blame, and c) the application of the labels sexual assault and sexual coercion.

Specifics: Study Population: Be sure to specify the regional population you are targeting in addition to other study characteristics. Participants will be women who have experienced coercive/assaultive events with male perpetrators. They must be at least 17 years old. They must speak/write in English. They will primarily come from North America, given the sampling methods used.

Participant Obligation: Participants must contact the primarily investigator for a link to the online study. They will answer several questionnaires and some qualitative questions. They can choose not to answer specific questions or to discontinue early.

Additional Notes: Compensation will either be $5.00 Tim Hortons gift card (for those who do not qualify or end the study early), or a $15.00 Tim Hortons gift card (for those who qualify and complete the study.

Development and Initial Feasibility Testing of Treatment for Sleep Disturbance in Women with Eating Disorders

Description: BACKGROUND: Recent evidence shows that sleep disturbance can predict the severity of eating disorder (ED) symptoms. This link suggests that improving sleep problems in ED populations is a viable pathway to improving ED symptoms. Cognitive behavioural therapy for insomnia (CBT-I) is the first-line treatment for sleep disturbance in psychiatric populations. Before introducing CBT-I to a new population, it is critical that it is adapted to the sleep-related thoughts and behaviours unique to that population. PROBLEM: Sleep-related thoughts and behaviours unique to ED populations remain unknown. PURPOSE: The present study assesses sleep-related thoughts and behaviours in ED populations to inform the development and initial feasibility of a behaviourally-based sleep intervention tailored specifically to ED populations. METHODS: A mixed-methods explanatory sequential design will be used, which includes an online survey followed by a virtual focus group. The study is shared via multiple media platforms dedicated to eating disorder awareness and recovery. We are recruit females, aged 18–50 years, and who report co-occurring insomnia and eating disorder symptoms. DATA ANALYSIS: The quantitative data will be analyzed using Statistical Package for the Social Sciences (SPSS, Version 25) and the qualitative data will be analyzed using thematic analysis

Specifics: Study Population:
Participants: Females, aged 18-50 years, who are not pregnant, and who are currently experiencing eating disorder symptoms and sleep disturbance.
Regional population: North America.
Sample size: Survey (N=200) and focus group (N=6).
Participant Obligation:
Obligation: online informed consent and survey with questions on thoughts and behaviours related to sleep and eating.
Optional: Express interest in participating in the focus group.

Couple HOPES (Helping Overcome PTSD and Enhance Satisfaction)

Description: Posttraumatic Stress Disorder (PTSD) will be a severe problem in Canada in the wake of COVID-19, especially for Military Members, Veterans, First Responders, and Healthcare Workers (MVFH). However, gold standard face-to-face PTSD treatments do not meet current MVFH needs, which requires virtual interventions and minimal healthcare resources. Recognizing the need for a virtual, low-resource PTSD intervention for MVFH with PTSD and their loved ones, the investigators developed Couple HOPES (Helping Overcome PTSD and Enhance Satisfaction). Couple HOPES is a secure, online self-help intervention for those with PTSD and their partners. However, MVFH are now particularly likely to be exposed to traumas related to COVID-19. It is essential to identify if Couple HOPES is safe and helpful for couples involving MVFH with COVID-19-related PTSD specifically. This project will therefore test the efficacy of Couple HOPES compared to a delayed waitlist control in 140 couples wherein one member is a MVFH with PTSD, half of whom have COVID-19-related PTSD. The investigators will examine if Couple HOPES is helpful in improving PTSD symptoms and relationship satisfaction for such couples, and if it is more or less helpful to this end for these couples compared to those with other forms of trauma exposure.

Specifics: Study Population:
The study population includes couples that have at least one member of the couple who is a service member, veteran, first responder, or healthcare worker with significant symptoms of PTSD.

Participant Obligation:
Both members of the couple must be willing to do intervention modules together, have a computer and access to high-speed Internet, have brief phone calls with a “coach” to help them use the online program, and complete online questionnaires.

How everyday experiences contribute to ethnic minority individuals’ wellbeing

Description: The objective of this two-phase study is to examine the relationship between coping responses to everyday challenges and wellbeing. For phase 1, participants will complete an online questionnaire. The online questionnaire will ask participants questions about their mental health status (e.g., anxiety, depression, post-traumatic stress symptoms) and how they cope with negative life events or challenges. The second phase of the study will consist of completing daily expressive writing activities for seven consecutive days. Participants will be asked to reflect on things that occurred earlier that day, while following guides to help them reflect on these events. The second phase of the study will also consist of completing three follow-up online questionnaires (2 weeks, 1 month, and 3 months after completing the writing program). Enrolment in phase 2 of the study requires the completion of the online questionnaire for phase 1. If participants are interested in enrolling in phase 2, they will have the opportunity to provide us with their email address to commence phase 2. This study has received ethical approval by the ethics board at the University of Ottawa.

Specifics: Study Population: Seeking individuals who are 16 years or older who can read and write well in English and who identify as ethnic minorities (e.g., Black/African-Canadians, Indigenous Canadians, East Asians) to partake in a two-part study.

Participant Obligation: It will take participants one hour to complete phase 1. For phase 2, it will take participants 10-15 minutes per day for seven days, in addition to four follow-up surveys that will each take one hour to complete.
