Perception and predictors of health locus of control at rehabilitation discharge and 1 year after traumatic spinal cord injury.

This retrospective study examined the perception and predictors of health locus of control (LOC) in 71 individuals with a spinal cord injury (SCI) at discharge from inpatient rehabilitation (average age 39 years, 77% male, 54% black, 51% cervical SCI, 51% incomplete SCI and average time post-SCI 20 days). We also determined if health LOC beliefs and predictors change over the 1st year after SCI in a representative subsample of 36 individuals. The participants completed surveys regarding the health LOC, self-esteem and depression whereas demographic and SCI information were retrieved from medical records. At inpatient discharge, 55% of SCI individuals endorsed the doctor LOC category compared to internal (14%), other people (6%), chance (3%) or multiple LOC categories (22%). A similar pattern was found at 1-year postinjury (doctor LOC 44% and non-doctor LOC combined 56%). A backward stepwise regression revealed that white race (P = 0.093), >12 years of education (P = 0.001) and cervical level of SCI (P = 0.033) were significant predictors of the doctor LOC category at inpatient discharge (overall classification accuracy 76%). Similarly, >12 years of education (P = 0.055), cervical level of SCI at inpatient discharge (P = 0.033) and higher self-esteem at 1-year post-SCI (P = 0.113) were significant predictors of the doctor LOC category at 1-year post-SCI (overall classification accuracy 78%). We conclude that health LOC remains stable over the 1st year after SCI with the majority of individuals believing that the control over outcomes of their health is in the hands of doctors. These findings have implications for the provision of rehabilitation services after SCI.

Multilevel modeling of self-esteem change during acute inpatient stroke rehabilitation.

OBJECTIVE: To explore self-esteem change during inpatient stroke rehabilitation and moderators of change. RESEARCH METHOD: One hundred twenty survivors of stroke serially completed the State Self-Esteem Scale (SSES) during inpatient rehabilitation, as well as measures of mood and perceived recovery as potential moderators of change. Age, gender, prior stroke, prestroke depression, stroke laterality, and admission Functional Independence Measure (FIM) self-care, mobility, and cognitive scores were also included as moderators. RESULTS: Multilevel modeling of the repeated administrations of the SSES indicated that self-esteem significantly improved during rehabilitation. Female gender, left hemisphere stroke, prior stroke, and lower admission FIM cognitive scores were associated with lower self-esteem ratings at admission, but only age and admission FIM self-care and mobility scores were associated with self-esteem change. Older individuals showed less self-esteem improvement than younger individuals, and higher self-care and mobility scores at admission were associated with greater self-esteem improvement. While mood change significantly covaried with self-esteem, the rate of mood change did not appear to influence rate of self-esteem change. Greater improvement in self-esteem over time was related to lower levels of perceived recovery, but this was likely because of the relationship between perceived recovery and self-esteem at rehabilitation admission. IMPLICATIONS: These results suggest that self-esteem improves during inpatient rehabilitation, and this change may be partially dependent on functional status. Implications for facilitating self-esteem change by the clinician are discussed, as well as future research directions.

Self-esteem level and stability, admission functional status, and depressive symptoms in acute inpatient stroke rehabilitation.

OBJECTIVES: Explore the relationship of self-esteem level, self-esteem stability, and admission functional status on discharge depressive symptoms in acute stroke rehabilitation. RESEARCH METHOD: One hundred twenty stroke survivors serially completed a measure of state self-esteem during inpatient rehabilitation and completed a measure of depressive symptoms at discharge. Functional status was rated at admission using the Functional Independence Measure (FIM). Regressions explored main effects and interactions of self-esteem level and stability and admission FIM self-care, mobility, and cognitive functioning on discharge depressive symptoms. RESULTS: After controlling for potential moderating variables, self-esteem level interacted with FIM self-care and cognitive functioning to predict discharge depressive symptoms, such that survivors with lower self-rated self-esteem and poorer functional status indicated higher levels of depressive symptoms. Self-esteem stability interacted with FIM mobility functioning, such that self-esteem instability in the presence of lower mobility functioning at admission was related to higher depressive symptoms at discharge. IMPLICATIONS: These results suggest that self-esteem variables may moderate the relationship between functional status and depressive symptoms. Self-esteem level and stability may differentially moderate functional domains, although this conclusion requires further empirical support.

Self-esteem stability and depressive symptoms in acute stroke rehabilitation: methodological and conceptual expansion.

OBJECTIVES: Explore the relationship of self-esteem level, self-esteem stability, and other moderating variables with depressive symptoms in acute stroke rehabilitation. MEASURES: One hundred twenty participants completed measures of state self-esteem, perceived recovery, hospitalization-based hassles, impairment-related distress, and tendency to overgeneralize negative self-connotations of bad events. Self-report of depressive symptoms was collected at admission and on discharge. Four regression analyses explored the relationship of self-esteem level and stability and each of 4 moderating variables (perceived recovery, hassles, impairment-related distress, and overgeneralization) with depressive symptoms at discharge. RESULTS: Analyses indicated significant 3-way interactions in the 4 regression models. In general, individuals with unstable high self-esteem endorsed greater depressive symptoms under conditions of vulnerability (e.g., lower perceived recovery) than did individuals with stable high self-esteem. Under conditions of vulnerability, participants with stable low self-esteem indicated the highest levels of depressive symptoms. IMPLICATIONS: Self-esteem level and stability interact with psychological, environmental, and stroke-specific variables to predict depressive symptoms at discharge from stroke rehabilitation. This suggests the viability of self-esteem stability in exploring depressive symptoms in this setting and the complexity of emotional adjustment early after stroke.

Classification schema of posttraumatic amnesia duration-based injury severity relative to 1-year outcome: analysis of individuals with moderate and severe traumatic brain injury.

OBJECTIVE: Early investigations classified traumatic brain injury (TBI) severity according to posttraumatic amnesia (PTA) duration, designating "greater than 7 days" as the most severe. PTA durations of more than 7 days are common in neurorehabilitation populations. Moreover, no study has derived a PTA severity schema anchored to late outcome. The purpose of this study was to develop a PTA severity classification schema. DESIGN: Prospective observational study. SETTING: Rehabilitation hospital. PARTICIPANTS: Sample included TBI Model System participants (N=280) with known or imputed PTA duration during acute hospitalization and 1-year productivity status. Participants were primarily male (70%), median age of 27 years; and the most common mechanism of injury was motor vehicle collisions (79%). For study purposes, 4 injury severity groups were identified by observing differences in productivity associated with different PTA durations. INTERVENTIONS: None. MAIN OUTCOME MEASURE: Productivity status at 1 year postinjury. RESULTS: Fisher exact test comparisons revealed significant differences among 3 of the groups. Most individuals with PTA fewer than 14 days had favorable 1-year outcome (68% productive), whereas worse outcomes were associated with PTA more than 28 days (18% productive). CONCLUSIONS: If validated by other investigators, the proposed schema will be useful in determining prognosis for late functional status based on PTA duration.

Self-esteem in an acute stroke rehabilitation sample: a control group comparison.

OBJECTIVE: To compare ratings of self-esteem and depressive mood in a sample of stroke survivors in an acute inpatient rehabilitation setting to those of a matched control group. DESIGN: Stroke survivors (n = 80) were matched on age and education to a group of neurologically intact community-dwelling control participants. Between-group analysis compared mean ratings of self-esteem and depressive measures. Within-group correlational analyses explored the relationship between self-esteem and mood. Between-group comparison of the correlations between self-esteem and mood explored differences in the strength of association between these constructs. Regression analyses explored the relationship of self-esteem measures after controlling for depressive mood. MAIN MEASURES: Visual Analogue Self-Esteem Scale, Rosenberg Self-Esteem Scale, Geriatric Depression Scale. RESULTS: Stroke survivors rated significantly lower mean levels of self-esteem on the Visual Analogue Self-Esteem Scale (37 versus 41) and the Rosenberg Self-Esteem Scale (21 versus 24) than the control group. Stroke survivors also rated higher mean levels of depressive mood on the Geriatric Depression Scale (9 versus 6). Significantly higher correlations between self-esteem and mood ratings were noted in the stroke group than in the control group. Lower self-esteem ratings do not appear to be a byproduct of depressive mood. CONCLUSIONS: Self-esteem is negatively impacted by stroke and is strongly, but independently, associated with depressive mood. Clinicians may better facilitate the emotional adjustment of the survivor by considering this facet of psychological impact and intervening to address self-esteem.
