In this investigation, we produced a new 8-scale measure of perfectionism called the Perfectionism Inventory (PI) that is designed to capture the important constructs provided by 2 existing Multidimensional Perfectionism Scale (MPS; Frost, Marten, Lahart, & Rosenblate, 1990; Hewitt & Flett, 1991b) measures, along with new perfectionism scales. In the results from 3 studies, we describe scale development, scale psychometric properties, and criterion-related validity evidence for the 8 PI scales: Concern Over Mistakes, High Standards for Others, Need for Approval, Organization, Parental Pressure, Planfulness, Rumination, and Striving for Excellence. We present relationships between the 8 PI scales, relevant MPS scales, and other criterion measures. Second-order exploratory and confirmatory analyses provide support for the 8-scale PI model as well as support for 2 composite PI factors labeled Conscientious Perfectionism and Self-Evaluative Perfectionism.

Soil degradation is a critical and growing global problem. As the world population increases, pressure on soil also increases and the natural capital of soil faces continuing decline. International policy makers have recognized this and a range of initiatives to address it have emerged over recent years. However, a gap remains between what the science tells us about soil and its role in underpinning ecological and human sustainable development, and existing policy instruments for sustainable development. Functioning soil is necessary for ecosystem service delivery, climate change abatement, food and fiber production and fresh water storage. Yet key policy instruments and initiatives for sustainable development have under‐recognized the role of soil in addressing major challenges including food and water security, biodiversity loss, climate change and energy sustainability. Soil science has not been sufficiently translated to policy for sustainable development. Two underlying reasons for this are explored and the new concept of soil security is proposed to bridge the science–policy divide. Soil security is explored as a conceptual framework that could be used as the basis for a soil policy framework with soil carbon as an exemplar indicator.

Perfectionism has been frequently associated with diverse negative psychological outcomes, but less frequently with positive psychological outcomes. This investigation reports multiple regression analyses based on survey data from 216 psychology students. These analyses indicate that adaptive perfectionistic strivings and maladaptive perfectionistic concerns predict desirable outcomes including psychological well-being, life satisfaction, and affect. That perfectionistic strivings predicted these outcomes is inconsistent with the small zero-order correlations between perfectionistic strivings and the positive outcomes, indicating that maladaptive perfectionistic concerns act as a suppressor variable in this relationship. These findings illustrate the importance of conceptualizing perfectionism as having both adaptive and maladaptive dimensions, and of assessing both simultaneously when examining relationships between perfectionism and other substantive variables.
