Qur'ān 16:112English sense: fear | Arabic sense: الخوف, خوف
وَضَرَبَ ٱللَّهُ مَثَلࣰ ا قَرۡيَةࣰ كَانَتۡ ءَامِنَةࣰ مُّطۡمَئِنَّةࣰ يَأۡتِيهَا رِزۡقُهَا رَغَدࣰ ا مِّن كُلِّ مَكَانࣲ فَكَفَرَتۡ بِأَنۡعُمِ ٱللَّهِ فَأَذَٰقَهَا ٱللَّهُ لِبَاسَ ٱلۡجُوعِ وَٱلۡخَوۡفِ بِمَا كَانُواْ يَصۡنَعُونَ
God presents the example of a town that was secure and at ease, with provisions coming to it abundantly from all places. Then it became ungrateful for God’s blessings, so God afflicted it with the garment of famine and fear, for what its people had done
Qur'ān 2:155English sense: fear | Arabic sense: الخوف, خوف

who begrudge you [believers] any help. When fear comes, you [Prophet] see them looking at you with eyes rolling like someone in their death throes; when fear has passed, they attack you with sharp tongues and begrudge you any good. Such men do not believe, and God brings their deeds to nothing- that is all too easy for God

Whenever news of any matter comes to them, whether concerning peace or war, they spread it about; if they referred it to the Messenger and those in authority among them, those seeking its meaning would have found it out from them. If it were not for God’s bounty and mercy towards you, you would almost all have followed Satan

And We will indeed try you with something of fear and hunger, and decrease of wealth, souls, and fruits; and give good news to the patient. The custom of the Lord is that whenever He threatens the servant and shows harshness in a verse, then, right after that or before it, He caresses the servant and gives him hope. Thus in this verse He breaks the servant by mentioning those harsh things and varieties of trial. Then He gives good news, He caresses, and He says, “and give good news to the patient.” And, at the beginning of these verses He says, “Surely God is with the patient” [2:153]. Glory be to Him! How gentle and how merciful He is to His servants! And We will indeed try you. He says, “We will test you, sometimes with fear, sometimes with dread, sometimes with poverty, sometimes with hunger, sometimes with outward affliction, sometimes with inward sorrow.” The outward trial and evide

The greatest terror shall not make them sorrow, and the angels will receive them: “This is the day that you were promised.” On the Day of Resurrection in the greatest gathering place and most tremendous courtyard, they will not hear from the angels the call “no good news” [25:22], nor the address, “Stand apart today, O offenders!” [36:59], nor the harsh call, “Slink into it, and do not talk to Me!” [23:108]. They will not hear the call of separation's pain, nor will they despair of mercy. Rather the angels will keep on coming, company after company, and they will give the good news: “This is the day that you were promised,” that is, “This is the day in which you have the promised reward.” Among them are those who will be received by the angels, and among them are those who will be addressed and made known by the King.

And Allah gives the example of a township (Makkah), it was secure and peaceful: its provision coming to it in abundance from every place, but it (its people) denied the favors of Allah. So Allah made it taste extreme hunger (famine) and fear, because of what they did (112)There has come to them a Messenger from among themselves, but they denied him, so the torment seized them while they were wrongdoers (113)
The Example of Makkah
This example refers to the people of Makkah, which had been secure, peaceful and stable, a secure sanctuary while men were being snatched away from everywhere outside of it. Whoever entered Makkah, he was safe, and he had no need to fear, as Allah said:

2476 to 2500 of 4,916Neurobiological substrates of cognitive rigidity and autonomic inflexibility in generalized anxiety disorder.
Generalized anxiety disorder (GAD) is characterized by difficulties in inhibiting both perseverative thoughts (worry and rumination) and autonomic arousal. We investigated the neurobiological substrates of such abnormal inhibitory processes, hypothesizing aberrant functional coupling within 'default mode' (DMN) and autonomic brain networks. Functional imaging and heart rate variability (HRV) data were acquired from GAD patients and controls during performance of three tracking tasks interspersed with a perseverative cognition (PC) induction. After detection of infrequent target stimuli, activity within putative DMN hubs was suppressed, consistent with a redirection of attentional resources from internal to external focus. This magnitude of activity change was attenuated in patients and individuals with higher trait PC, but was predicted by individual differences in HRV. Following the ind…

Amygdala functional connectivity as a longitudinal biomarker of symptom changes in generalized anxiety.
Generalized anxiety disorder (GAD) is characterized by excessive worry, autonomic dysregulation and functional amygdala dysconnectivity, yet these illness markers have rarely been considered together, nor their interrelationship tested longitudinally. We hypothesized that an individual's capacity for emotion regulation predicts longer-term changes in amygdala functional connectivity, supporting the modification of GAD core symptoms. Sixteen patients with GAD (14 women) and individually matched controls were studied at two time points separated by 1 year. Resting-state fMRI data and concurrent measurement of vagally mediated heart rate variability were obtained before and after the induction of perseverative cognition. A greater rise in levels of worry following the induction predicted a stronger reduction in connectivity between right amygdala and ventromedial prefrontal cortex, and enha…

Alterations in Amygdala-Prefrontal Functional Connectivity Account for Excessive Worry and Autonomic Dysregulation in Generalized Anxiety Disorder.
Background: Generalized anxiety disorder (GAD) is characterized by the core symptom of uncontrollable worry. Functional magnetic resonance imaging studies link this symptom to aberrant functional connectivity between the amygdala and prefrontal cortex. Patients with GAD also display a characteristic pattern of autonomic dysregulation. Although frontolimbic circuitry is implicated in the regulation of autonomic arousal, no previous study to our knowledge combined functional magnetic resonance imaging with peripheral physiologic monitoring in these patients to test the hypothesis that core symptoms of worry and autonomic dysregulation in GAD arise from a shared underlying neural mechanism.
Methods: We used resting-state functional magnetic resonance imaging and the measurement of parasympathetic autonomic function (heart rate variability) in 19 patients with GAD and 21 control subjects to …

Patterns of alpha asymmetry in those with elevated worry, trait anxiety, and obsessive-compulsive symptoms: A test of the worry and avoidance models of alpha asymmetry.
Some authors have argued that worry cues lateralization of frontal brain activity leftward, whereas other varieties of avoidance motivation cue lateralization of frontal brain activity rightward. By comparison, more right-than-left parietal activity correlates with anxious arousal. The purpose of the present report was to test two models of brain lateralization and anxiety: one model that proposed that worry correlates with more left-frontal activity and another model that proposed that avoidance motivation (including worry) correlates with more right-frontal activity. Undergraduate students were selected for worry, obsessive-compulsive symptoms, and trait anxiety using self-report questionnaires. A subset of participants also met DSM-IV criteria for Generalized Anxiety Disorder (GAD) or Obsessive-Compulsive Disorder (OCD). Alpha asymmetry and also a global-power-adjusted metric of alpha…

Gray and white matter volume abnormalities in generalized anxiety disorder by categorical and dimensional characterization.
Increasing efforts have been made to investigate the underlying pathophysiology of generalized anxiety disorder (GAD), but only limited consistent information is available on gray (GM) and white matter (WM) volume changes in affected adults. Additionally, few studies employed dimensional approaches to GAD pathology. This study compares structural brain imaging data from n=19 GAD subjects and n=24 healthy comparison (HC) subjects, all medication-free and matched on age, sex and education. Separate categorical and dimensional models were employed using voxel-based morphometry for GM and WM. Significantly higher GM volumes were found in GAD subjects mainly in basal ganglia structures and less consistently in the superior temporal pole. For WM, GAD subjects showed significantly lower volumes in the dlPFC. Largely consistent findings in dimensional and categorical models point toward these st…

Worry and Rumination in Generalized Anxiety Disorder and Obsessive Compulsive Disorder.
Ample work has already been conducted on worry and rumination as negative thought processes involved in the etiology of most of the anxiety and mood related disorders. However, minimal effort has been exerted to investigate whether one type of negative thought process can make way for another type of negative thought process, and if so, how it subsequently results in experiencing a host of symptoms reflective of one or the other type of psychological distress. Therefore, the present study was taken up to investigate whether rumination mediates the relationship between worry and generalized anxiety disorder (GAD), and between worry and obsessive compulsive disorder (OCD) in two clinical groups. Self-report questionnaires tapping worry, rumination, generalized anxiety disorder (GAD), and obsessive compulsive disorder (OCD) were administered to a clinical sample of 60 patients aged 30-40. W…

Do Metacognitions and Intolerance of Uncertainty Predict Worry in Everyday Life? An Ecological Momentary Assessment Study.
Cognitive models of generalized anxiety disorder (GAD) suggest that excessive worry is due to positive and negative metacognitive beliefs and/or intolerance of uncertainty. Empirical support mainly derives from cross-sectional studies with limited conclusiveness, using self-report measures and thereby possibly causing recall biases. The aim of the present study therefore was to examine the power of these cognitive variables to predict levels of worry in everyday life using Ecological Momentary Assessment (EMA). Metacognitions and intolerance of uncertainty were assessed using well-established self-report questionnaires in 41 nonclinical participants who subsequently completed ratings on worry intensity and burden on a portable device for 1week at seven times a day once every 2hours. Results showed significant associations of negative metacognitive beliefs and intolerance of uncertainty, …

Episodic future thinking in generalized anxiety disorder.
Research on future-oriented cognition in generalized anxiety disorder (GAD) has primarily focused on worry, while less is known about the role of episodic future thinking (EFT), an imagery-based cognitive process. To characterize EFT in this disorder, we used the experimental recombination procedure, in which 21 GAD and 19 healthy participants simulated positive, neutral and negative novel future events either once or repeatedly, and rated their phenomenological experience of EFT. Results showed that healthy controls spontaneously generated more detailed EFT over repeated simulations. Both groups found EFT easier to generate after repeated simulations, except when GAD participants simulated positive events. They also perceived higher plausibility of negative-not positive or neutral-future events than did controls. These results demonstrate a negativity bias in GAD individuals' episodic f…

Background: Generalized anxiety disorder (GAD) is a common psychiatric disorder characterized by long-term worry, tension, nervousness, fidgeting, and symptoms of autonomic system hyperactivity. The neurobiology of this disorder is still unclear, although it has been shown consistently that the environment and the genetic profile could increase its risk. We examined whether a polymorphism in the brain-derived neurotrophic factor (BDNF) gene, which plays a role in neuroplasticity and memory, could increase the vulnerability to this disorder.
Participants and methods: In our study, 816 participants from a population-based study were genotyped by qPCR for the BDNF functional variant rs6265 (Val66Met) and the BDNF serum levels were measured by ELISA.
Results: Our results showed a significant association between the Met allele and risk for GAD (P=0.014), but no differences were observed in th…

Metacognitions, worry and sleep in everyday life: Studying bidirectional pathways using Ecological Momentary Assessment in GAD patients.
Background: The metacognitive model of generalized anxiety disorder proposes that negative metacognitive beliefs are crucial in the maintenance of excessive worry. Furthermore, according to the cognitive model of insomnia, worry leads to problems falling or staying asleep and poor sleep quality. In order to test the assumed causal relationships, the present study examined the time-dependent course of negative metacognition and worry as well as worry and sleep quality, using Ecological Momentary Assessment (EMA).
Method: Negative metacognitions, worry and sleep were assessed by self-report questionnaires as well as EMA in 56 GAD patients who carried a portable device for 1 week and logged sleep quality, negative metacognition and worry processes four times a day.
Results: Metacognitions, worry and sleep were significantly correlated. Structural equation modeling using multilevel analyses …

Health anxiety and the non-medical use of prescription drugs in young adults: A cross-sectional study.
Introduction: Studies have demonstrated a relation between health anxiety (hypochondriasis) and substance use, but this minimal body of literature has focused on alcohol or illicit drugs. The use of medications without a physician's prescription (i.e., non-medical use of prescription drugs, NMUPD) is increasingly prevalent among young adults. Health anxiety, a tendency to worry excessively about health, is a factor that could contribute to NMUPD, but this has not been examined. The purpose of the current study was to examine the relations among health anxiety, NMUPD, and other psychological variables related to substance use.
Methods: In the present study, young adult college students (N = 758), ages 18-25, completed an anonymous online survey assessing demographics, health anxiety, NMUPD, and other psychological characteristics, including depression and general anxiety.

Predictive Risk Factors for Fear of Hypoglycemia and Anxiety-Related Emotional Disorders among Adolescents with Type 1 Diabetes.
Objective: To explore the fear of hypoglycemia (FOH) and anxiety-related emotional disorders and their risk factors among adolescents with type 1 diabetes mellitus (T1DM).
Subjects and methods: A cross-sectional study was conducted among 187 adolescents (aged 13-18 years; 92 males, 95 females) with T1DM at the Diabetes Treatment Center, Prince Sultan Military Medical City, Riyadh, Saudi Arabia, from June 2013 to February 2014. The participants were interviewed using FOH and Screen for Child Anxiety-Related Disorders (SCARED) scales.
Results: Females had significantly higher scores on all FOH and SCARED subscales compared to males. The mean scores for many subscales of FOH and SCARED were higher in the older age group (16-18 years), in those under multiple-dose injection (MDI) treatment (compared with the insulin pump treatment), and in those with a longer duration of T1DM.

Psychometric properties of abbreviated and ultra-brief versions of the Penn State Worry Questionnaire.
The Penn State Worry Questionnaire (PSWQ) is a 16-item self-report measure considered the gold-standard assessment instrument for worry. Two abbreviated versions of the PSWQ have also been developed. An 8-item measure (PSWQ-A) was designed to address poor model fit of the full version with older adult samples, and a 3-item version (PSWQ-3) was developed in a clinical setting to avoid problems related to the reverse-scored items and to increase clinical utility. Preliminary examinations of the abbreviated forms have been promising, but additional psychometric evaluation is needed to confirm their reliability and validity. The current study compared psychometric properties of the 3 versions of the PSWQ in a heterogeneous clinical sample of 272 patients presenting for treatment in a partial hospital setting. Results suggested that scores for all 3 versions had good internal consistency; con…

The ages of anxiety--differences across the lifespan in the default mode network functional connectivity in generalized anxiety disorder.
Objectives: Generalized anxiety disorder (GAD) is one of the most prevalent anxiety disorders, but its neural basis is relatively understudied. This study aims to characterize the functional connectivity in the default mode network (DMN) in GAD across the lifespan.
Design and settings: Functional and structural magnetic resonance imaging data were collected with subjects at rest. We analyzed the resting state functional connectivity patterns in the DMN for 27 GAD participants and 39 non-anxious comparison participants. Using a two-way analysis of variance, we explored the interaction between age and GAD status on functional connectivity. In GAD participants, we analyzed the correlation of functional connectivity indices with the duration of illness and worry severity.
Results: The age-by-anxiety interaction showed a greater anxiety effect on the functional connectivity between the poster…

CALM Pregnancy: results of a pilot study of mindfulness-based cognitive therapy for perinatal anxiety.
Many women experience anxiety during pregnancy with potential negative effects on maternal, birth, and child outcomes. Because of potential risks of fetal exposure to psychotropic medications, efficacious non-pharmacologic approaches are urgently needed. However, no published studies of psychotherapeutic treatments for anxiety in pregnancy exist. Mindfulness-based cognitive therapy (MBCT) may substantially reduce anxiety and co-morbid symptoms in people with anxiety disorders. Coping with Anxiety through Living Mindfully (CALM) Pregnancy is an adaptation of MBCT designed to address anxiety in pregnant women. This study examined the feasibility, acceptability, and clinical outcomes of the CALM Pregnancy intervention in pregnant women anxiety. Twenty-four pregnant women with generalized anxiety disorder (GAD) or prominent symptoms of generalized anxiety participated in an open treatment tr…

Worrying and rumination are both associated with reduced cognitive control.
Persistent negative thought is a hallmark feature of both major depressive disorder and generalized anxiety disorder. Despite its clinical significance, little is known about the underlying mechanisms of persistent negative thought. Recent studies suggest that reduced cognitive control might be an explanatory factor. We investigated the association between persistent negative thought and switching between internal representations in working memory, using the internal shift task (IST). The IST was administered to a group of undergraduates, classified as high-ruminators versus low-ruminators, or high-worriers versus low-worriers. Results showed that high-ruminators and high-worriers have more difficulties to switch between internal representations in working memory as opposed to low-ruminators and low-worriers. Importantly, results were only significant when the negative stimuli used in th…

Reduced hippocampal N-acetyl-aspartate (NAA) as a biomarker for overweight.
Objective: We previously demonstrated an inverse relationship between both dentate gyrus neurogenesis - a form of neuroplasticity - and expression of the antiapoptotic gene marker, BCL-2 and adult macaque body weight. We therefore explored whether a similar inverse correlation existed in humans between body mass index (BMI) and hippocampal N-acetyl-aspartate (NAA), a marker of neuronal integrity and putatively, neuroplasticity. We also studied the relationship of a potentially neurotoxic process, worry, to hippocampal NAA in patients with generalized anxiety disorder (GAD) and control subjects (CS).
Methods: We combined two previously studied cohorts of GAD and control subjects. Using proton magnetic resonance spectroscopy imaging ((1)H MRSI) in medication-free patients with GAD (n = 29) and a matched healthy control group (n = 22), we determined hippocampal concentrations of (1) NAA (2)…

Intolerance of uncertainty mediates the relation between generalized anxiety disorder symptoms and anger.
Previous research has shown that individuals with generalized anxiety disorder (GAD) report elevated anger compared with nonanxious individuals; however, the pathways linking GAD and anger are currently unknown. We hypothesized that negative beliefs about uncertainty, negative beliefs about worry and perfectionism dimensions mediate the relationship between GAD symptoms and anger variables. We employed multiple mediation with bootstrapping on cross-sectional data from a student sample (N = 233) to test four models assessing potential mediators of the association of GAD symptoms to inward anger expression, outward anger expression, trait anger and hostility, respectively. The belief that uncertainty has negative personal and behavioural implications uniquely mediated the association of GAD symptoms to inward anger expression (confidence interval [CI] = .0034, .1845, PM = .5444), and the b…

Generalized anxiety disorder is associated with overgeneralization of classically conditioned fear.
Background: Meta-analytic results of fear-conditioning studies in the anxiety disorders implicate generalization of conditioned fear to stimuli resembling the conditioned danger cue as one of the more robust conditioning markers of anxiety pathology. Due to the absence of conditioning studies assessing generalization in generalized anxiety disorder (GAD), results of this meta-analysis do not reveal whether such generalization abnormalities also apply to GAD. The current study fills this gap by behaviorally and psychophysiologically assessing levels of conditioned fear generalization across adults with and without GAD.
Methods: Twenty-two patients with a DSM-IV-Text Revision diagnosis of GAD and 26 healthy comparison subjects were recruited and tested. The employed generalization paradigm consisted of quasi-randomly presented rings of gradually increasing size, with extreme sizes serving …

The Perinatal Anxiety Screening Scale: development and preliminary validation.
The purpose of this study is to develop a scale (Perinatal Anxiety Screening Scale, PASS) to screen for a broad range of problematic anxiety symptoms which is sensitive to how anxiety presents in perinatal women and is suitable to use in a variety of settings including antenatal clinics, inpatient and outpatient hospital and mental health treatment settings. Women who attended a tertiary obstetric hospital in the state of Western Australia antenatally or postpartum (n = 437) completed the PASS and other commonly used measures of depression and anxiety. Factor analysis was used to examine factor structure, and ROC analysis was used to evaluate performance as a screening tool. The PASS was significantly correlated with other measures of depression and anxiety.

Observing nonreactively: a conditional process model linking mindfulness facets, cognitive emotion regulation strategies, and depression and anxiety symptoms.
Background: Mindfulness-based interventions for depression and anxiety emphasize the importance of observing present moment experience, but observing has often been positively related to anxiety and unrelated to depression symptoms. The current study sought to better understand the conditions and mechanism through which observing relates to symptoms by examining six conditional process models in which (1) nonreactivity moderates the direct effect of observing on symptoms of anxiety and depression symptoms and (2) nonreactivity moderates the indirect effect of observing on anxiety and depression via cognitive emotion regulation strategies (i.e., rumination, worry, and reappraisal).

Are attentional control resources reduced by worry in generalized anxiety disorder?
This is the first study to examine attentional control capacities in generalized anxiety disorder (GAD). GAD is characterized by uncontrollable worry. Individuals diagnosed with GAD and healthy participants (HPs) performed a random key-pressing task while thinking about a worrisome or a positive future event, to assess the extent to which attentional control resources are used by worry. Attentional control was also assessed when participants were not instructed to think about a specific topic using the N-back task, which varies in task difficulty, and therefore is sensitive to subtle differences in ability to handle increasing demands on attentional control within the same paradigm. GAD participants (but not HPs) were less random while worrying than thinking about a positive event during the key-pressing task, suggesting that worry consumed more attentional control resources in this popu…

Methods: Twenty-one (n=21) adults with a principal diagnosis of GAD and eleven (n=11) non-anxious healthy controls (HC) underwent functional magnetic resonance imaging while completing a facial emotion processing task. Responses to threat-related emotionality (i.e., the contrast of fear and angry vs. happy faces) were assessed at pretreatment and again following 10 sessions of CBT in the GAD group and a comparable waiting period in the HC group.
Results: At pretreatment, GAD participants displayed blunted responses in the amygdala, insula, and anterior cingulate to the happy face-processing comparison condition, and greater amygdalo-insular connectivity. CBT was associated with attenuated amygdalar and subgenual anterior cingulat…
