Exploratory analyses are an important first step in psychological research, particularly in problem-based research where various variables are often included from multiple theoretical perspectives not studied together in combination before. Notably, exploratory analyses aim to give first insights into how items and variables included in a study relate to each other. Typically, exploratory analyses involve computing bivariate correlations between items and variables and presenting them in a table. While this is suitable for relatively small data sets, such tables can easily become overwhelming when datasets contain a broad set of variables from multiple theories. We propose the Gaussian graphical model as a novel exploratory analyses tool and present a systematic roadmap to apply this model to explore relationships between items and variables in environmental psychology research. We demonstrate the use and value of the Gaussian graphical model to study relationships between a broad set of items and variables that are expected to explain the effectiveness of community energy initiatives in promoting sustainable energy behaviors.

Ageing of the population in European cities creates fundamental challenges with regard to employment, pensions, health care and other age-related services. Many older people want to live independent lives as long as possible. This aspiration is currently strongly supported by many local governments. A precondition for 'ageing in place' is that older people perceive their neighbourhoods as familiar and safe places. In the Netherlands, many neighbourhoods with an ageing population have been subject to urban restructuring policies. An important question is to what extent such policies affect the housing situation, socioeconomic position and social support networks of older people, as these factors strongly assist their ability to 'age in place'. The paper answers this question through an exploratory analysis of a small but unique panel data set from Hoogvliet, a large urban restructuring area in the city of Rotterdam. The partly counter-intuitive results show that restructuring has enabled 'ageing in place'. Compared to stayers, movers within Hoogvliet often report improved housing quality and positive neighbourhood change. The exploratory analyses did not provide evidence of decreased social support or increased loneliness through restructuring-induced disruptions of social ties. Various 'buffer measures' have been effective in preventing negative restructuring impacts on older residents.

Objectives This exploratory study was conducted to find out how well the concept of evidence-based research (EBR) is known among European health researchers with substantial clinical research experience, and which barriers affect the use of an EBR approach. The concept of EBR implies that researchers use evidence synthesis to justify new studies and to inform their design. Design A cross-sectional exploratory survey study. Setting and participants The survey was conducted among European health researchers. Respondents included 205 health researchers (physicians, nurses, dentists, allied health researchers and members of other professions involved in health research) with a doctoral degree or at least 5 years of research experience. Primary and secondary outcome measures The primary outcome measures were the level of awareness of the concept of EBR and the presence of barriers affecting the use of an EBR approach. Secondary outcome measures include correlations between sociodemographic characteristics (eg, profession) and awareness of EBR. Results We discovered that 84.4% of the respondents initially indicated their awareness of the concept of EBR. Nevertheless, 22.5% of them concluded that, on reading the definition, they either do not know or do not fully comprehend the concept of EBR. The main barriers affecting the use of an EBR approach were related to organisational issues, such as not being attributed resources (30.5% of the respondents), time (24.8%) or access to implement it (14.9%). Conclusions Despite the limitations, this study clearly shows that ongoing initiatives are necessary to raise awareness about the importance of implementing the EBR approach in health research. This paper contributes to a discussion of the issues that obstruct the implementation of the EBR approach and potential solutions to overcome these issues, such as improving the knowledge and skills necessary to practice the EBR approach.
