- Description: Aim: To illustrate how limitations in the cannabis literature undermine our ability to understand cannabis-related harms and problems experienced by users and identify users at increased risk of experiencing adverse outcomes of use. Method and results: Limitations have been organized into three overarching themes. The first relates to the classification systems employed by researchers to categorize cannabis users, their cannabis use and the assumptions on which these systems are based. The second theme encompasses methodological and reporting issues, including differences between studies, inadequate statistical control of potential confounders, the under-reporting of effect sizes and the lack of consideration of clinical significance. The final theme covers differing approaches to studying cannabis use, including recruitment methods. Limitations related to the nature of the data collected by researchers are discussed throughout, with a focus on how they affect our understanding of cannabis use and users. Conclusions: These limitations must be addressed to facilitate the development of effective and appropriately targeted evidence-based public health campaigns, treatment programmes and preventative, early intervention and harm minimization strategies, and to inform cannabis-related policy and legislation. © 2010 The Authors, Addiction © 2010 Society for the Study of Addiction.

- Description: Cannabis is one of the most common illegal psychoactive substance used in European countries, in particular among adolescents and young adults (1). It has been estimated that almost 55% of adolescents aged 15–19 years have used cannabis at least once in their lifetime (2), while past year use is reported by approximately 30% of 15–17 year olds and over 47% of those aged 18–19 years (3). Cannabis use has been associated with several adverse life outcomes including unemployment, legal problems, dependence, early school leaving, increased risk of developing both psychotic and affective disorders (3, 4) together with brain structural and functional abnormalities (5, 6). An association between cannabis use, psychiatric disorders and suicidal behavior has also frequently been reported, although the exact nature of this link is still poorly understood (4).

- Description: A growing body of research suggests that some time perspective orientations are more beneficial than others with regard to well-being. However, little is known about the factors affecting the development of these time perspectives. This gap in the research was addressed through two studies. Study 1 (N = 218; M = 29.8 years, SD = 11.45) identified ZTPI past positive (PP) as a beneficial time perspective and past negative (PN) as a detrimental time perspective. Structural equation modelling was then used in Study 2 (N = 443; M = 31.2 years, SD = 13.0) to develop two models of the associations between attachment orientation, basic psychological need satisfaction and PP and PN, respectively. While anxious and avoidant attachment orientation were associated with both PP and PN, the three basic psychological needs were differentially associated. The findings of these studies suggest the importance of early childhood care to the development of beneficial time perspectives.

- Description: While a growing number of researchers are embracing Internet-based data collection methods, the adoption of Internet-based recruitment methods has been relatively slow. This may be because little is known regarding the relative strengths and weaknesses of different methods of Internet-based participant recruitment, nor how these different recruitment strategies impact on the data collected. These issues are addressed in this article with reference to a study comparing the effectiveness of three Internet-based strategies in recruiting cannabis users for an online study. Consideration of the recruitment data leads us to recommend that researchers use multipronged Internet-based recruitment campaigns with appropriately detailed recruitment messages tailored to the population of interest and located carefully to ensure they reach the intended audience. Further, we suggest that building rapport directly with potential participants, or utilising derived rapport and implicit endorsements, is an important aspect of successful Internet-based participant recruitment strategies. © 2011 Journal of Research Practice and the author.

- Description: Recently, a shortened version of the Zimbardo Time Perspective Inventory (ZPTI; Zimbardo & Boyd, 1999) was proposed as a “gold standard” (Sircova et al., 2014, p. 9). In this study, we examined the internal consistency and structural validity of this version of the ZPTI in samples of adolescents from the United Kingdom (N = 913) and the United States (N = 815), and adults from Australia (N = 667). Results provided support for the internal consistency of ZPTI scores, but structural validity analyses indicated poor fit and numerous problematic items. The findings call into question the use of scores on this shortened version of the ZTPI.

- Description: As an individual difference variable assessing the extent to which attitudes towards past, present and future influence behavior, time perspective is a potentially useful construct. However, its development and utility has been compromised by measurement issues. Recently, a short form of the Zimbardo Time Perspective Inventory (ZTPI), the SZTPI-15 has been suggested to yield valid and reliable scores. Using three independent samples from America, Australia, and the United Kingdom, the present study tested the psychometric properties of SZPTI-15 scores. Confirmatory factor analyses did not support the 5-factor structure and internal consistency estimates for four of the subscales were low. Fit indices obtained from exploratory structural equation modeling were better, suggesting that permitting items to load on multiple factors improved model fit. Correlations with variables shown to be related to ZTPI factors broadly supported the concurrent validity of the SZTPI-15. Results suggest that further psychometric examination of SZTPI-15 scores is required.

- Description: Background: University students are often perceived to have a privileged position in society and considered immune to ill-health and disability. There is growing evidence that a sizeable proportion experience poor physical health, and that the prevalence of psychological disorders is higher in university students than their community peers. This study examined the physical and mental health issues for first year Australian rural university students and their perception of access to available health and support services. Methods. Cross-sectional study design using an online survey form based on the Adolescent Screening Questionnaire modeled on the internationally recognised HEADSS survey tool. The target audience was all first-year undergraduate students enrolled in an on-campus degree program. The response rate was 41% comprising 355 students (244 females, 111 males). Data was analysed using standard statistical techniques including descriptive and inferential statistics; and thematic analysis of the open-ended responses. Results: The mean age of the respondents was 20.2 years (SD 4.8). The majority of the students lived in on-campus residential college style accommodation, and a third combined part-time paid work with full-time study. Most students reported being in good physical health. However, on average two health conditions were reported over the past six months, with the most common being fatigue (56%), frequent headaches (26%) and allergies (24%). Mental health problems included anxiety (25%), coping difficulties (19.7%) and diagnosed depression (8%). Most respondents reported adequate access to medical doctors and support services for themselves (82%) and friends (78%). However the qualitative comments highlighted concerns about stigma, privacy and anonymity in seeking counselling. Conclusions: The present study adds to the limited literature of physical and mental health issues as well as barriers to service utilization by rural university students. It provides useful baseline data for the development of customised support programs at rural campuses. Future research using a longitudinal research design and multi-site studies are recommended to facilitate a deeper understanding of health issues affecting rural university students. © 2013 Hussain et al.; licensee BioMed Central Ltd.

- Description: The Zimbardo Time Perspective Inventory (ZTPI; Zimbardo & Boyd, 1999) assesses five time-related constructs - Past Negative (PN), Past Positive (PP), Present Fatalistic (PF), Present Hedonistic (PF), and Future (F) - and is one of the most frequently used time measures in the extant literature. Versions of the ZTPI have been translated into a variety of languages, but the psychometric support for ZTPI scores remains contested. We examined the internal consistency, structural validity, and convergent validity of scores on a version of the ZTPI that consisted only of items that specifically referenced time constructs, the ZTPI-TP. Participants consisted of five samples of adolescents and adults from four countries: Australia (653 adults), Slovenia (425 adolescents and adults), the United Kingdom (913 adolescents; 455 adults), and the United States (815 adolescents). Structural validity analyses provided stronger support for ZTPI-TP scores than for ZTPI scores, and convergent validity evidence also provided support for ZTPI-TP scores. However, analyses revealed that the PF and PH factors were still problematic, especially with regard to factor coefficients and internal consistency estimates. We concluded that the ZTPI-TP can form the basis for a more robust version of the ZTPI.

- Description: Objective: Comorbidity between anxiety and cannabis use is common yet the nature of the association between these conditions is not clear. Four theories were assessed, and a fifth hypothesis tested to determine if the misattribution of stress symptomology plays a role in the association between state-anxiety and cannabis. Methods: Three-hundred-sixteen participants ranging in age from 18 to 71 years completed a short online questionnaire asking about their history of cannabis use and symptoms of stress and anxiety. Results: Past and current cannabis users reported higher incidence of lifetime anxiety than participants who had never used cannabis; however, these groups did not differ in state-anxiety, stress, or age of onset of anxiety. State-anxiety and stress were not associated with frequency of cannabis use, but reported use to self-medicate for anxiety was positively associated with all three. Path analyses indicated two different associations between anxiety and cannabis use, pre-existing and high state-anxiety was associated with (i) higher average levels of intoxication and, in turn, acute anxiety responses to cannabis use; (ii) frequency of cannabis use via the mediating effects of stress and self-medication. Conclusion: None of the theories was fully supported by the findings. However, as cannabis users reporting self-medication for anxiety were found to be self-medicating stress symptomology, there was some support for the stress-misattribution hypothesis. With reported self-medication for anxiety being the strongest predictor of frequency of use, it is suggested that researchers, clinicians, and cannabis users pay greater attention to the overlap between stress and anxiety symptomology and the possible misinterpretation of these related but distinct conditions. © 2014 Temple, Driver and Brown.

- Description: The Zimbardo Time Perspective Inventory (ZTPI) has been extensively used, with more than 1,400 citations in Scopus alone. After identifying psychometric problems however, several authors have attempted to overcome limitations by shortening the scale. As such, there now exist multiple. shortened versions of the ZTPI, all using some of the original 56 items. Although each shorter version reports various broadly acceptable validity parameters using the group with which it was developed, these are often sample specific and at the cost of reliability, generalizability, and ability to detect individual differences in the construct. To examine this more closely, we reviewed the psychometric properties of the ZTPI and some of its derivatives, and found that data-driven approaches to creating these shortened versions of the scale prioritized improved model fit over internal reliability and sensitivity. In conclusion, we suggest that it is time for a new collaborative strategy to address conceptual and measurement concerns with the ZTPI, and discourage data-driven and sample-specific solutions to the psychometric concerns of the scale's scores. More broadly, we recommend that researchers consider the impact on reliability, generalizability, and ability to detect individual differences when developing short psychometric scales. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Elizabeth Temple” is provided in this record**
