The link between the nature of the human–companion animal relationship and well-being outcomes in companion animal owners

Research into the impact of companion animals on well-being has been both extensive and inconclusive, with studies finding both positive and negative relationships. The present research explored three previously unexamined relationship science concepts that may help clarify whether companion animals provide well-being benefits: self-expansion (the process of adding positive content to the self through incorporating new resources and perspectives into one’s identity or engaging in novel, exciting activities), perceived pet responsiveness, and perceived pet insensitivity; as well as attachment. We focused on dog and cat owners’ depression, anxiety, positive and negative affect, and loneliness through an online survey with a large sample population (N = 1359). We found that perceived pet insensitivity is a significant positive predictor of depression, anxiety, negative affect, and loneliness; that attachment is a significant positive predictor of depression, anxiety, and loneliness, and a significant negative predictor of positive affect; and that self-expansion is a significant positive predictor of positive affect, and a significant negative predictor of loneliness. Loneliness emerged as a mediator in the relationship between perceived pet insensitivity, attachment, self-expansion, and all mental well-being outcome variables. These findings indicate that perceived pet insensitivity, attachment, and self-expansion may play an important yet neglected role in well-being outcomes

The association between attachment to companion animals and depression:A systematic review

There is significant literature related to companion animal attachment and depression, but to date, there has not been a systematic review of it. The aims of this systematic review were threefold: (1) to compare depression outcomes between pet and non-pet owners; (2) to identify the prevalence of how attachment is operationalized within the human–pet relationships literature, as it is defined in two distinct, divergent ways: as an attachment bond or as an attachment orientation; and (3) to review and synthesize the existing literature related to the association between pet attachment and depression. A search of five databases (Pubmed, Medline, Web of Science, Embase, and PsycInfo) was conducted in January 2024 to locate articles (journal articles, dissertations) focusing on pets, attachment, and depression or depressive symptoms that met predefined inclusion and exclusion criteria. In total, 40 studies were included in the review. Eighteen studies compared depression outcomes in pet owners and non-pet owners; of these, 14 found no significant difference in depression between the two groups, while four found that pet owners were significantly less depressed than non-pet owners. Most studies measuring attachment bond revealed a positive or non-significant relationship with depression, while the majority of studies measuring attachment orientation indicate that higher levels of secure attachment are negatively associated with depression, while higher levels of attachment insecurity are typically positively associated with depression. We conclude that the field needs more clarification regarding the definition of attachment so that meaningful conclusions regarding the impact of pet attachment on mental health can be drawn.</p

Development and validation of the Companion Animals Self-Expansion Scale

Abstract Although many people experience a close and complex relationship with their companion animals, our understanding and measurement of this relationship has lagged far behind that of human-human relationships. Important advances in human-human relationship concepts and measurement have yet to be applied in the context of human-companion animal relationships, including the critically relevant concept of self-expansion (i.e. the process through which positive content is added to the self). The aim of this research was to develop and validate a new full and short-form measure of self-expansion within the human-companion animal relationship, the Companion Animals Self-Expansion Scale (CASES). The sample included in the exploratory factor analysis (EFA) phase consisted of 366 adult English-speaking companion animal owners, while the sample included in the confirmatory factor analysis (CFA) phase consisted of 368 adult English-speaking companion animal owners. All participants completed demographic questions and the CASES. Analyses revealed the full version of the CASES to be 15 items, six of which were retained for the short form of the scale based on their consistently high-factor loadings and theoretically relevant content. The CASES, as well as its short form, the CASES-SF, are both reliable and valid in measuring self-expansion within the human-companion animal relationship
