Abstract

Objective:

To investigate the impact of neurocognitive functioning on the self-focused processing styles of rumination and reflection, and the relationship to mood symptoms after severe traumatic brain injury (TBI).

Design:

A cross-sectional design with a between-group component comparing self-focused processing styles and mood symptoms of adults with TBI and age- and gender-matched controls.

Method:

Fifty-two participants with severe TBI (75% male, M age = 36.56, SD = 12.39) completed cognitive tests of attention, memory, executive functioning and the Awareness Questionnaire, Reflection and Rumination Questionnaire (RRQ), and Depression, Anxiety, and Stress Scales (DASS - 21). Fifty age- and gender-matched controls completed the RRQ and DASS-21.

Results:

TBI participants reported significantly greater mood symptoms than controls (p < .05); however, levels of rumination and reflection did not significantly differ. TBI participants high on both reflection and rumination had significantly greater mood symptoms than those with high reflection and low rumination (p < .001). Higher levels of rumination and reflection were associated with better working memory and immediate and delayed verbal memory (r = .36-.43, p < .01). Higher levels of rumination were also associated with greater verbal fluency, self-awareness, and mood symptoms (r = .36-.70, p < .01).

Conclusions:

Individuals with better memory functioning may be more likely to engage in self-focused processing after severe TBI. Reflection without ruminative tendencies is more adaptive for mental health than reflection with rumination.

Practitioner Points:

Individuals with severe TBI report more mood symptoms than non-injured controls but do not differ on self-focused processing. Poorer memory function is related to lower levels of rumination and reflection. Reflection without ruminative tendencies is adaptive for mental health after severe TBI. Individuals with greater self-awareness and ruminative tendencies are at increased risk of mental health problems following severe TBI.

Limitations:

Rumination and reflection were assessed using a self-report measure which assumes that people with severe TBI are able to reliably report on self-focused processing styles. The direction of associations between self-focused processing, self-awareness, and mood symptoms could not be determined due to the cross-sectional design.

Relationship Formation

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Traits, Mood, and Subjective Wellbeing

Traits, Mood, and Subjective Wellbeing

Subjective well-being (SWB) refers to an individual's self-evaluation of their overall life satisfaction, happiness, and fulfillment. This multifaceted construct is typically assessed by analyzing the balance of positive and negative emotions alongside perceptions of life satisfaction. Personality traits such as neuroticism and extraversion are strongly associated with variations in SWB, offering critical insights into the underlying mechanisms of emotional well-being.
Neuroticism and...

Ending Relationships

Ending Relationships

The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

Diabetes: Symptoms, Diagnosis, and Complications

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Negative and Cognitive Symptoms of Schizophrenia

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Relationship Growth

Relationship Growth

Interpersonal relationships progress through stages, beginning with awareness and moving toward mutuality, where emotional connections deepen. While many relationships remain at moderate levels of mutuality, deeper connections form through self-disclosure, trust, and interdependence.Self-DisclosureSelf-disclosure involves revealing personal information, starting with surface-level details and gradually progressing to more intimate content. As trust grows, individuals feel more comfortable...
