Description

The Inventory of Complicated Spiritual Grief (ICSG) is a specialized psychometric instrument designed to assess complicated spiritual grief, a form of grief in which bereavement is accompanied by significant spiritual or religious distress. Unlike conventional grief measures that primarily evaluate emotional, cognitive, and behavioral reactions to loss, the ICSG specifically examines disruptions in an individual’s spiritual beliefs, relationship with the sacred, sense of meaning, and existential worldview following the death or loss of a significant person. It is widely used in bereavement research, clinical psychology, pastoral care, palliative medicine, and spiritual care to identify individuals experiencing profound spiritual suffering during the grieving process.

The questionnaire evaluates several core dimensions of spiritual grief, including:

  • Spiritual Doubt – questioning previously held religious or spiritual beliefs following bereavement.
  • Loss of Spiritual Meaning and Purpose – diminished sense of life’s meaning, direction, or purpose after loss.
  • Search for Meaning – efforts to reconstruct meaning and integrate the experience of bereavement into one’s worldview.
  • Spiritual Distress – feelings of abandonment, anger toward God or a higher power, or disruption in one’s spiritual life.
  • Emotional Impact of Spiritual Grief – psychological consequences associated with unresolved spiritual conflict during mourning.

The ICSG is grounded in theories of meaning reconstruction, religious coping, existential psychology, and spiritual well-being, recognizing that grief may profoundly influence an individual’s spiritual identity and worldview.

Analysis and Use of Data

The ICSG enables researchers and clinicians to quantify the severity of spiritual grief and examine its relationship with psychological adjustment, religious coping, mental health, and bereavement outcomes.

Statistical analyses commonly include:

  • Descriptive statistics (means, standard deviations, medians, frequencies, and percentile distributions).
  • Reliability assessment using Cronbach’s alpha and McDonald’s Omega.
  • Construct validity evaluation through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA).
  • Assessment of convergent and discriminant validity using measures of complicated grief, spiritual well-being, religiosity, meaning in life, depression, anxiety, resilience, and quality of life.
  • Correlation analyses using Pearson’s or Spearman’s correlation coefficients.
  • Group comparisons using independent-samples t-tests, ANOVA, MANOVA, or appropriate non-parametric procedures.
  • Multiple linear and logistic regression analyses to identify predictors of spiritual grief.
  • Mediation, moderation, and Structural Equation Modeling (SEM) to investigate relationships among bereavement, spirituality, coping, and psychological outcomes.
  • Longitudinal analyses examining changes in spiritual grief during bereavement and following therapeutic interventions.

The ICSG is widely applied in:

  • Bereavement research
  • Clinical psychology
  • Health psychology
  • Palliative and hospice care
  • Pastoral counseling
  • Spiritual care
  • Nursing research
  • Quality-of-life and end-of-life studies

Objective

The primary objective of the ICSG is to provide a reliable and valid assessment of the spiritual dimension of grief following significant loss. The questionnaire helps identify individuals experiencing spiritual conflict, loss of meaning, or disruption of religious beliefs during bereavement, thereby supporting both research and clinical intervention.

More specifically, the questionnaire aims to:

  • Assess the severity of complicated spiritual grief.
  • Evaluate spiritual doubt and existential distress following bereavement.
  • Measure loss of spiritual meaning and purpose.
  • Examine the relationship between spirituality and grief adjustment.
  • Identify individuals who may benefit from spiritually integrated counseling or psychotherapy.
  • Evaluate the effectiveness of bereavement and spiritual care interventions.
  • Advance research on spirituality, meaning reconstruction, and psychological adaptation following loss.

Scoring

The ICSG consists of a series of self-report items assessing multiple dimensions of spiritual grief. Participants typically respond using Likert-type rating scales, indicating the degree to which each statement reflects their current experience following bereavement. Depending on the instrument version, response options generally range from strong disagreement to strong agreement or from low to high frequency.

Item scores are summed or averaged to generate an overall spiritual grief score. Higher total scores indicate greater levels of spiritual distress, stronger disruption of spiritual beliefs, increased existential questioning, and more severe complicated spiritual grief. Some versions may also calculate scores for individual dimensions of spiritual grief.

Psychometric evaluation of the ICSG commonly includes:

  • Internal consistency reliability (Cronbach’s alpha and McDonald’s Omega)
  • Test–retest reliability
  • Construct validity
  • Convergent and discriminant validity
  • Factorial validity using Confirmatory Factor Analysis (CFA)
  • Measurement invariance across religious affiliations, cultures, and demographic groups
  • Item analysis and corrected item–total correlations
  • Responsiveness to therapeutic and bereavement interventions

Higher scores generally reflect more severe spiritual distress and unresolved existential suffering associated with bereavement, whereas lower scores indicate greater spiritual adjustment, meaning reconstruction, and healthier adaptation following loss.
