Fear of Religious Sin
Scrupulosity
A therapist treating scrupulosity faces a problem no other obsessive-compulsive presentation produces. Praying repeatedly, studying doctrine intensively and worrying about damnation are, in the relevant traditions, things devout people do. Deciding which instances are compulsions requires knowing what the tradition normally asks, and clinicians therefore collaborate with clergy.
The material sets out three purposes for that collaboration and the third is the one that matters here: to bolster the patient's trust in the process, to fortify their understanding that the thoughts are disordered, and to help clinicians disentangle normative religious practices from disordered ones. Nobody outside a tradition can draw that line.
What scrupulous obsessions and compulsions look like
The obsessions recorded are:
- fears about having blasphemous thoughts
- fears of having unwittingly committed an immoral act
- fears of being condemned to hell
- fears of having performed a religious obligation improperly
The compulsions follow the shape of the fear: excessive prayer, obsessive study of doctrine, and avoidance of religious obligations and objects, which is the one that inverts.
Two features make it distinctive. People with scrupulosity often exhibit paralysing doubt about whether they fully understand their own moral principles, which produces rumination with nothing to resolve it. And they may have difficulty interpreting exaggerated language in religious contexts, which is a specific perceptual problem in traditions built on hyperbole, parable and warning.
It is not confined to religious people. Where it occurs in the irreligious it manifests as fears of being immoral or bad.
Why scrupulosity is named after a pebble
Scrupulosity comes from scruple, from the Latin scrupulum, a small rock or pebble, of the kind that gets into a shoe while walking. The sense of mental uneasiness followed from that.
Then a second shift, in the jargon of apothecaries, made a scruple one twenty-fourth of an ounce: a weight noticeable only on extremely sensitive scales. In parallel, vernacular English took scruple to mean an inconsequential moral interpretation that could only trouble an oversensitive mind.
Both senses describe the condition precisely, and both arrived before anybody was describing it clinically.
Whether scrupulosity is really a form of OCD
The majority position treats scrupulosity as a subtype of obsessive-compulsive disorder, and under a four-prong model of OCD it falls among obsessions of unacceptable thoughts seeking reassurance-based compulsions. A five-prong model based on factor analysis puts it with religious, sexual and aggressive obsessions, with no explicit compulsion model.
Since the early 1990s some clinicians have pushed for a separate diagnosis, and their case is specific. Patients with scrupulosity show poorer insight, higher fixity of belief, greater perceptual aberration and more severe magical ideation than other OCD patients.
There is a second and sharper argument. In OCD generally, obsessions depart from real-life problems and compulsions are irrational acts intended to reduce anxiety. In scrupulosity the obsessions concern pertinent real-life problems, and the compulsions, while excessive, are logically informed and aimed at settling the matter once and for all. A person praying repeatedly to be certain of forgiveness is doing something that follows from the premises.
The counter-argument is functional. The overwhelming similarity to OCD holds despite topographical differences, other unacceptable-thoughts presentations use nearly identical neutralisation strategies and follow similar cycles, co-occurrence with sexual and violent obsessions is common, and obsessions shift theme across a lifetime, so a person may have scrupulous obsessions in childhood and a different unacceptable-thoughts category as an adult.
Why scrupulosity resists treatment more than other OCD
Scrupulosity responds worse than other conditions on the obsessive-compulsive spectrum and is more resistant to treatment overall.
The mental energy consumed by obsessions and compulsions leads to increased comorbidity, particularly depressive and other anxiety disorders. People with scrupulosity are at higher risk of depression, low self-esteem, self-harm and suicide.
That is a harder set of outcomes than most entries in this catalogue carry, and it belongs in the same paragraph as the treatment difficulty rather than separately: a condition that resists treatment accumulates cost while the treatment is being attempted.
What exposure therapy asks of a scrupulous patient
Cognitive behavioural therapy and exposure and response prevention are the common approaches. Selective serotonin reuptake inhibitors may be prescribed where symptoms are severe enough.
Exposure and response prevention here means confronting the feared thought and not performing the compulsion, which for a person who believes the compulsion is what prevents damnation is a considerable thing to ask. It is a further reason the clergy involvement is not a courtesy: a patient who trusts that their tradition permits what the therapy requires can attempt it, and one who does not, cannot.
Which beliefs turn a thought into an act
Four dysfunctional beliefs are named, and each is a mechanism rather than a mood:
- undue emphasis on the role of one's own thoughts
- an excessive need for control
- a heightened sense of responsibility
- an impaired ability to estimate threats
The first and the third together produce the condition's central experience: a thought is treated as an act, and the person is answerable for it.
Told apart
Often confused with Fear of Religious Sin
- Fear of GodFear of God is a theological category with a positive sense in several traditions, meaning reverence. Scrupulosity is a clinical condition in which the fear has become an obsession with compulsions attached, and telling the two apart is precisely why clinicians consult clergy.
- Holy AnorexiaAnorexia mirabilis organised religious devotion around food restriction centuries before scrupulosity was named, and the question of where devotion ends and disorder begins is the same one in both.
- Fear of GermsMysophobia was coined in 1879 to describe an obsessive-compulsive case of hand-washing, and scrupulosity is the same structure with a moral rather than a physical contaminant.
Common questions
Questions about Scrupulosity
- Why do clinicians work with clergy?
- Because somebody has to tell a devout practice from a compulsive one. Praying repeatedly and studying doctrine intensively are things devout people do, and a therapist outside the tradition cannot say which instances are excessive. Clergy also help build the patient's trust in treatment and support the work in ecclesiastical settings.
- Where does the word come from?
- From the Latin scrupulum, a small rock or pebble of the kind that gets into a shoe, which acquired a sense of mental uneasiness. Apothecaries later made a scruple one twenty-fourth of an ounce, a weight visible only on very sensitive scales, and vernacular English took it to mean an inconsequential moral point that only an oversensitive mind would notice.
- Is it a separate condition from OCD?
- The majority view says no and the argument for yes is specific. Patients with scrupulosity show poorer insight, higher fixity of belief, greater perceptual aberration and more severe magical ideation. Their obsessions concern pertinent real-life problems rather than departing from them, and their compulsions are excessive but logically informed and aimed at settling the matter.
- Can non-religious people have it?
- Yes, and the presentation shifts accordingly. In irreligious people it manifests as fears of being immoral or bad rather than as fears about doctrine or damnation, which suggests the structure is prior to the content.
- How well does it respond to treatment?
- Worse than other conditions on the obsessive-compulsive spectrum, and it is described as more resistant overall. The mental energy the obsessions and compulsions consume increases comorbidity, particularly depression and other anxiety disorders, and the risk of low self-esteem, self-harm and suicide is raised.
- What makes exposure treatment difficult here?
- What it asks. Exposure and response prevention means confronting the feared thought and not performing the compulsion, and for somebody who believes the compulsion is what prevents damnation that is a considerable request. A patient whose clergy confirm the tradition permits it can attempt it, and one without that confirmation may not.
